Sri Lanka's opening batsman Sanath Jayasuriya will undergo an MRI scan in Colombo on Sunday after dislocating his right shoulder during a one-day match against India.
He suffered the injury on Saturday after diving to stop a drive from India's Yuvraj Singh and had to be helped from the field by the team's physiotherapist.
With his shoulder heavily strapped, the 36-year-old batted with the aid of painkillers to guide Sri Lanka to a three-wicket win and finished unbeaten on 43.
Sri Lanka Cricket's Australian surgeon Dr David Young was watching the game from the grandstand and was able to click the shoulder back into place.
But concerns remained about the damage caused to Jayasuriya's rotator cuff tendon.
"We will need to do an MRI scan on Sunday to find out what damage has been done to the rotator cuff," Young told reporters.
"The worse case scenario is a full thickness tear that would require surgery and stop him playing for a significant period of time."
Jayasuriya dislocated the same shoulder in a one-day tournament in Morocco back in 2002 and has been suffering from tendon stiffness and soreness since, according to Young.
Jayasuriya risked aggravating the injury by opting to bat but said he was satisfied with his decision.
"There was a lot of pressure out there and we needed me to finish the game with the lower order so it was one of the most memorable innings of my career," Jayasuriya told reporters.
"At the start the pain was bad and I could not pull or cut but it then eased after 20 minutes after the pain-killing injection started to take effect."
