On Saturday, in DC's must-win game against Mumbai Indians, a strategic blunder cost the team a spot in the play-offs.
Delhi Capitals lost to Mumbai Indians by 5 wickets to finish fifth in the league.
Invited to bat, DC posted 159/7, courtesy Mitchell Marsh's 48-ball 63, and then restricted Punjab to 142/9.
Marsh smashed the only half-century of the match as Delhi defended a modest 159/7 against Punjab to record their first back-to-back victories this season.
Marsh top scored with 89 runs while Warner was unbeaten on 52.
Moeen Ali bagged three wickets after Devon Conway's 87 had given CSK a total of 208/6.
It is understood that the batter experienced intense fever which likely forced the Capitals' medical staff to move him out of the team hotel.
It is the second time during the IPL 2022 that the Delhi team has been forced into isolation.
Powell, who hit a breathtaking 67 not out off 35 balls in DC's 21-run win here on Thursday, also spoke about his chat with teammate David Warner, who was closing in on a century, in the final over of the innings.
