Impact Player Rule In IPL
There are many important rules in the Indian Premier League, and the impact player rule is one of them. It was introduced in the IPL in 2023 by the Board of Control for Cricket in India (BCCI).
Maybe you’ve seen an IPL game where a player who wasn’t initially in the lineup walks onto the pitch to bat or bowl. That’s the impact rule in play right there. But that’s the basics. There’s still a lot more to know about the rule and how it works in the IPL.
So, in this blog post, we explain the impact player meaning in cricket, the official regulations, and when it’s applicable. We also outline some of the most successful impact players in the history of the IPL.
How Does Impact Player Rule Work in IPL?
The meaning of impact player in IPL is pretty straightforward once you see it in action. When two IPL teams play, each captain is expected to provide a list of their starting 11 players before the toss. However, they also list five “substitute” players who sit on the bench.
The initial eleven players, or starting 11, begin the match. But as the game proceeds, the captain can call any of the five “substitute” players to come in and replace someone from the starting 11. Once a player leaves the pitch and a substitute replaces them, they cannot return to the game.
The new player (from the substitutes’ list) is the impact player. Once they come onto the pitch, they can do everything a regular player does. That is, they can bat and even bowl their full four overs.
Why Do Teams Bring on an Impact Player?
Now that we know what is imp in IPL, we can deduce why the rule was put in place. The most obvious reason for this replacement rule is to make matches more dynamic and strategic. While the rule appears to give teams an advantage, it also comes at a cost. Captains have to decide carefully before bringing on an impact player. That’s because the change is permanent for the rest of the game.
Another reason for the impact player rule in cricket is to help the substitute team. Just like football teams can substitute players in the game, IPL teams can also make changes to strengthen their positions. For example, if a team is batting and they lose too many wickets, they can bring in an extra batsman from the list of their five substitutes to save the innings.
Similarly, if they are bowling and the pitch is helping spin, they can bring on a fast bowler for a spinner. This tactical substitution improves their chances and keeps the game alive until the very last ball.
Impact Player Rules and Regulations in IPL
The impact player regulation sounds simple on the surface. However, it comes with some strict rules and regulations as stipulated by the BCCI. This is to ensure teams and captains do not just swap players whenever they feel like it.
General Guidelines
Here are the general guidelines for the IPL impact player regulation:
One per Team: Each IPL team can only use one impact player per match.
Five on Bench: Each IPL team must name five substitutes on the bench before the game, and their one impact player must come from these five.
The 11-Player Limit: Even though the impact player steps into action as a 12th man, only 11 players can be on the field at any point in time.
Timing of Substitution: The impact player can come on before the innings start or during the innings. It all depends on the team's strategy.
Permanent Substitution: Once a team introduces an impact player, that player cannot be replaced.
The “Four Overseas Player” Limit
This is perhaps the most technical of the impact player regulations for fans, online cricket betting players, and enthusiasts. The BCCI stipulates that an Indian Premier League team can have only four foreign players in its starting 11 at any point in the game.
This brings us to the question: can a foreign player be an impact player in IPL? The answer depends on the team’s starting lineup. If a team already has four overseas regular players on the field, they can only bring an Indian player as the impact player. But if they started with only three foreign players, they could bring in a fourth foreign player from the bench as their impact player.
When Can Impact Player Be Used in IPL?
The impact rule in IPL allows teams to bring on their impact player at specific moments in the match. It’s one of the betting markets available on 1xBet when placing a wager on IPL matches. A team can use an impact player in one of the following cases.
Before the innings start or between innings, right before the first ball of the first or second innings
After the end of an over, just after the 6th ball is bowled, before the start of the next over
When a wicket falls immediately after a batter is dismissed
At the end of the powerplay after the 6.0 over
If a batter retires injured or retires out
Flexibility is one reason the rule is so important in T20 cricket. Teams can choose any of these moments to make their move, depending on what’s happening in the game.
For instance, if a team is chasing and loses early wickets, their impact player might be a batsman just before the start of an innings. On the other hand, if the team is defending a total, their impact player might be a bowler to help control the middle overs.
Most Successful Impact Players in IPL
The IPL impact rule has been around for a while. And within that period, it has turned some players into “super-subs.” While these players might not make the starting 11, they come off the bench to completely change the game's impact.
Jos Buttler (Rajasthan Royals / Gujarat Titans)
Jos Buttler is one of the few players who have made a significant impact in the Indian Premier League as a substitute. For example, in the 2024 season, while playing for the Rajasthan Royals, Buttler scored an unbeaten 107 from 60 balls against the Kolkata Knight Riders after being introduced as an impact player. He later moved to the Gujarat Titans in the 2025 season, where he continued his fine form.
Mitchell Marsh (Lucknow Super Giants)
Mitchell Marsh had one of the standout stats from the 2025 season. After moving to LSG, Marsh was used frequently as an Impact Player at the top of the order. He couldn’t bowl due to a back injury he was just recovering from. By late April 2025, Marsh had amassed 229 runs in 6 matches in that role. He finished the full 2025 season with 627 total runs.
Matheesha Pathirana (Chennai Super Kings / Kolkata Knight Riders)
Pathirana also makes the list as one of the most successful impact players we’ve seen in the IPL. In 2024, he was the Chennai Super Kings’ impact sub as a bowler. He took 8 wickets in his first three substitute appearances in that season, including a 4/28 spell against the Mumbai Indians. Pathirana has signed with the Kolkata Knight Riders for the 2026 season.
Sai Sudharsan (Gujarat Titans)
Sudharsan played as an impact player frequently for the Gujarat Titans in the early half of the 2024 season. As an extra batter off the bench to replace a bowler, he accumulated 127 runs in his first three innings. He eventually became a regular in the starting eleven and even went on to win the Orange Cap in 2025 with a record-breaking 759 runs.
Vaibhav Arora (Kolkata Knight Riders)
Arora has been KKR’s go-to impact player for some time. He often comes on during the Powerplay when KKR bowled second. In 2024, he took 11 wickets with an excellent strike rate in those early overs. Arora’s impact player exploits have been supported by his ability to swing the ball both ways.
Shivam Dube (Chennai Super Kings)
Analysts often call Dube the “Face of the Impact Player Regulation,” and that’s not an exaggeration. Between 2023 and 2024, CSK almost exclusively used him as a mid-innings sub to take down spin. This substitution rule worked so well for the CSK because they could pack their lineup with more bowlers without sacrificing Dube’s middle-order power.
