Zimbabwe elected to bowl first after winning the toss in the second T20 against Sri Lanka in Colombo on Tuesday.
Sri Lanka, who lead the three-match series 1-0, made one change to the side that won the opening game on Sunday, bringing in Dilshan Madushanka in place of Nuwan Thushara.
The left-arm quick was overlooked for the opening game after featuring in the three-match ODI series, but he is back in the side after Thushara struggled in the first T20 of the series.
Zimbabwe opted to play the same team that featured in the first game.
The final match will be played in Colombo on Thursday.
