Australia paceman Mitchell Starc came off the field with a suspected cut knee in a further blow to the hosts in the first Ashes Test against England.
The left-armer was stepped on by Shaun Marsh while fielding at the Gabba in Brisbane on day two on Friday.
Starc quickly left the field with what appeared to be a bloody knee and cut pants, although he seemed to be in no obvious discomfort. He returned soon after.
The speedster had figures of 1-55, with England 231-4 in their first innings.
It added to the injury worries carried into the series opener by David Warner (neck) and Marsh (back).
