St Mirren goalkeeper Shamal George could miss Sunday's Scottish Cup semi-final clash against Celtic.
George had to be replaced after half an hour at Celtic Park last weekend, when he was caught by striker Tomas Cvancara, and was replaced by substitute Ryan Mullen for the remainder of the 1-0 defeat to Martin O'Neill's side.
The 28-year-old had been training today in preparation for a repeat of December's League Cup final when they meet Celtic at Hampden but has picked up an issue during the session.
"We need to assess it," interim manager Craig McLeish said of the extent of George's injury.
"He's only just went over his ankle so we're hoping that he's going to be okay. Ryan [Mullen] came in at the weekend and did great in place of Shamal throughout the game.
"If Ryan steps in [on Sunday] then we're more than comfortable and confident with what Ryan can do as well. We need to wait on Shamal's update and whoever's in goal for us, we're confident."
