IPL 2023: Why did KKR, PBKS name an overseas player in the list of subs despite four in first XI?
According to the rules, the Impact Player can only be an Indian player unless there are less than 4 overseas players in the Playing XI.

There was a little bit of surprise when both Kolkata Knight Riders and Punjab Kings named an overseas player in the list of substitutes despite having four overseas players in the playing XI.
As per the playing conditions issued by the league, neither Matthew Short nor David Wiese can be used as Impact Player. Because, the Impact Player can only be an Indian player unless there are less than 4 overseas players in the Playing XI.
So, assuming the franchises were aware of this, why did they use up one of the five substitute spots with an overseas slot?
That is because, to even be a substitute fielder for a match, the player has to named in the XI plus five subs list. The easiest way to understand is that: a) the list of subs named after the toss is NOT a list of Impact Players. It is just a list of subs. b) At no point in the match there can be five overseas players as part of the proceedings.
