The Bangladesh left-arm pace bowler picked eight wickets in as many games in IPL 2022.
Mustafizur averaged 30.50 and maintained an economy rate of 7.63 in the recently concluded cash-rich league.
Mustafizur yielded 28 runs in an over against Dinesh Karthik and smashed four boundaries and a couple of sixes in the carnage.
Delhi Capitals have the presence of left-arm pacers in the domestic ranks of Khaleel Ahmed and Chetan Sakariya, so they might release Mustafizur, who was purchased for his base price of INR 2 crore.
