Prasanna Jayawardene injures thumb

Prasanna Jayawardene has suffered a hairline fracture to the top of his right thumb after being hit by a Mitchell Johnson bouncer during Sri Lanka's first innings at the MCG. That delivery was the last Jayawardene faced, as the ball caught the shoulder of the bat after hitting his thumb, and ballooned to Phillip Hughes in the slip cordon. Jayawardene made 24.

Team management are yet to determine whether Jayawardene will keep wickets on day two, but in the meantime Kumar Sangakkara has taken the gloves in his stead, and will keep for the remainder of day one.

Sri Lanka's 12th man Dinesh Chandimal also keeps wickets, but cannot stand in behind the stumps as he is a substitute. A year ago, he replaced Jayawardene on Sri Lanka's tour of South Africa as wicketkeeper-batsman.

"There was some bruising on his thumb after his innings, so we thought we'd better check," team manager Charith Senanayake said, before X-rays revealed the extent of the injury.
