Sri Lanka's Twenty20 World ​Cup campaign ​was dealt another blow on ​Wednesday when Matheesha Pathirana was ruled out of the rest of the tournament ‌due to ⁠a ⁠muscle strain in his left leg, ​with Dilshan Madushanka approved as a replacement.

Pathirana, 23, ​collapsed clutching his left leg in his first over in the ​Group B clash ⁠with Australia ‌in Pallekele on Monday.

A ​trusted ​bowler in the death ⁠overs, he limped off and never ​returned as Sri Lanka registered ​an eight-wicket victory.

This is the second major injury blow Sri Lanka have had to endure after wrist-spin all-rounder Wanindu Hasaranga ‌was ruled out with a hamstring injury that he picked ​up ​in the ⁠side's tournament opener against Ireland.

Sri Lanka next play Zimbabwe in Colombo in their ​final Group B fixture on Thursday before their first Super Eight game against England on Sunday.
