Sri Lanka's selection committee have sent Lasith Malinga home from the Indian Premier League for rehabilitation to a knee injury.
The bowler had named himself as unavailable for the upcoming three-Test tour of England - due to start in Cardiff on May 26 - because of the complaint.
However Malinga has continued to play for the Mumbai Indians in the IPL with the problem.
And chairman of selectors Duleep Mendis has now written to Malinga asking him to return to Sri Lanka to start a rehabilitation programme immediately.
"It looks a bit awkward when someone says he is injured and continues to play cricket," he said.
"That is the reason why we have decided to write to Malinga and ask him to return home and undergo a rehabilitation programme.
"Malinga has specifically added that he is not available for Test matches right now because he has a nagging knee problem.
"When the player says that he is injured and has to undergo a rehab programme what we can do is tell him to undergo it immediately, without continuing to play cricket in the IPL, and then get ready for cricket in Sri Lanka if he is interested in playing for his country."
Having played in only two Tests since touring England in 2007, Malinga has focused on the one-day game and Sri Lanka cricket secretary Nishantha Ranatunga is worried.
"We are very much concerned about Malinga because he is an important product in the team," Ranatunga added.
"He should be up and running to play in all three formats of the game. In that sense getting him fit and ready to play at full strength is very important."
