After snaring two wickets, Shakib returned to score a 65-ball 82 to lead his side to their second victory in the tournament.
Bangladesh are facing several injury concerns within the team.
Bangladesh fast bowler Rubel Hossain has been ruled out of the second Test against Pakistan starting on Wednesday due to a side strain, the country's cricket board said.
Hosts Bangladesh were on Monday dealt a telling blow as their strike bowler Mustafizur Rahman was ruled out of the Asia Cup due to a Grade I side strain sustained during the home team's win against Sri Lanka. "Bangladesh pace bowler Mustafizur Rahman has suffered a side strain and will not play any further part in the Micromax Asia Cup T20," a BCB release stated. A Grade I side strain can also make him a doubtful starter for Bangladesh's World T20 qualifying round matches against the Netherlands and the Ireland in Dharamsala.
There was some bad news in the Bangladesh camp ahead of their big Asia Cup Twenty20 final against India with vice-captain and top all-rounder Shakib Al Hasan sustaining a "left hip-flex injury" in a training session. Shakib was hit by a delivery in his left thigh region and was seen applying ice-pack yesterday. He also walked with a slight limp and looked in pain. He tried to practice on Saturday but did not continue for long. The dilemma in the Bangladesh camp is whether to play Shakib in Sunday's match and risk aggravating his injury before the World T20 qualifiers in Dharamsala. T eam physio Bayjedul Islam, however, expressed confidence that the senior player will be available in the big match.
