Pakistan Super League (PSL) Chairman Najam Sethi on Tuesday announced that PSL will be using the decision review system (DRS) in the playoff matches, becoming the first T20 league in the history of cricket to use the review system.

The PSL chairman made the announcement through his official Twitter account saying, "Another first from HBL PSL. DRS to be used in the playoff matches."

The decision to implement DRS comes after umpires were scrutinised for making poor on-field judgements multiple times in the tournament.

The DRS will allow teams to question the on-field umpire's decision.

Under the system, both sides are allowed a limited number of unsuccessful challenges before they are barred from requesting a referral for the remainder of an innings.

But, in order to not delay the game, they must make it clear within a matter of seconds of the umpire's original verdict whether they wish to call on DRS.

In an exact replica of inaugural season, the playoff line-ups are same as they were last year. Quetta will head into Tuesday's fixture playing Peshawar at the Sharjah Cricket Stadium in a sombre mood following two narrow losses against Islamabad United ─ who will face in the second playoff against Karachi Kings at the same venue 24 hours later.
