St Johnstone boss Callum Davidson has provided an injury update on Michael O'Halloran after the winger was forced off against Celtic yesterday.

The former Rangers man was involved in a coming together with Hoops skipper Scott Brown and he was unable to continue.

On the extent of O'Halloran's injury, Saints manager Davidson told Saints TV: "Michael got studs down the side of his hip.

"His hip seized up and he has massive big stud marks and there's a bit of swelling there.

"We will need to have a look at that this week."

Following yesterday's draw he added: “It’s a really tough place to come and we were missing two or three key players. But to get a point is a little bit bitter-sweet.

“We go 1-0 up and Zander makes a couple of great saves to keep us in the game. To take a point at Parkhead, I am delighted for the players.”
