Delhi Capitals have announced that Australia all-rounder Mitch Marsh has been admitted to hospital after testing positive for Covid-19. Apart from Marsh, four members of Delhi Capitals members in the bio-bubble, including support staff, have also returned positive tests. However, they are asymptomatic. "The Delhi Capitals medical team is closely monitoring Marsh's condition," the <a href="https://www.thenationalnews.com/sport/ipl/" target="_blank">IPL</a> franchise said in a statement. "All remaining members of the bubble are currently in isolation in their respective rooms, and will be tested regularly." Marsh will need to isolate for at least a week and will miss at least the games against the Punjab Kings on Wednesday and against Rajasthan Royals on Saturday. However, these fixtures could be in jeopardy in case the situation worsens. Delhi physio Patrick Farhart tested positive for the virus last week but no other cases were reported as Delhi went on to play their game against Royal Challengers Bangalore at the weekend. Matches in this year's IPL are being played across four venues in Mumbai and Pune with 50 percent capacity crowds allowed inside stadiums. As a result of the latest tests, Delhi Capitals' next match has been shifted from Pune to Mumbai. The venue was changed "to avoid any further incident due to any undetected case during a long-distance bus journey in a closed environment," BCCI secretary Jay Shah said in a statement. "The Covid positive cases are under isolation and medical observation." They would have to clear two negative tests to return to the team's bio-secure bubble, Shah added. The whole contingent will undergo another round of RT-PCR testing before the match at the Brabourne Stadium.
