In an unexpected turn of events, Kusal Mendis has been appointed as the 26th captain of the Sri Lanka national cricket team for One Day Internationals (ODIs). 

This decision comes as regular captain Dasun Shanaka has been sidelined from the squad due to an injury. Mendis, a seasoned player with a strong track record, will now lead the Sri Lankan team for the remainder of their World Cup campaign. 

The management has high hopes for Mendis, who has consistently performed well in previous matches and has proven his leadership skills. 

In another significant roster adjustment, all-rounder Chamika Karunaratne has been chosen as Shanaka's replacement in the squad. Karunaratne's versatility and impressive performance in domestic cricket have earned him a spot in the national team. His inclusion is expected to bolster the team's performance in both batting and bowling. 

However, the Sri Lankan team has faced yet another setback with the injury of fast bowler Matheesha Pathirana. Pathirana is expected to be out of action for at least a week due to a shoulder injury. This leaves the team with challenges in the fast bowling department, as they will have to rely on other bowlers to fill the void left by Pathirana. 

Despite these setbacks, the Sri Lankan team remains determined and focused on their upcoming match against Australia tomorrow. The match is of crucial importance for both teams, as they vie for a spot in the next stage of the tournament. Sri Lanka will be looking to Mendis and Karunaratne to lead the team to victory and keep their World Cup dreams alive.
