New Delhi: Mohammed Shami's T20I comeback will be delayed as the veteran pace bowler has tested positive for COVID 19 and will be out of the Australia series starting in Mohali from September 20.

Veteran pacer Umesh Yadav, who played last of his seven T20Is in 2019 against Australia is back in the scheme of things, having recovered from a quadriceps injury.

"Yes, Shami has tested COVID-19 positive. But there is nothing to worry as the symptoms are mild. But he will have to remain in isolation and will be able to rejoin the squad once he tests negative. It is unfortunate but that is how life is," a senior BCCI source told PTI on conditions of anonymity.
