Forster eyes future in England
St Mirren manager Danny Lennon has a number of injury concerns to contend with as he prepares for the visit of Dundee United this weekend.
Jim Goodwin's calf complaint makes him 'touch and go' and he will be handed a late test before a decision is made on his participation.
Gary Teale is making a good recovery from his abductor problem and Steven Thompson (groin) also comes into contention, but Lee Mair is out with a stomach injury and could miss the League Cup final on Sunday week.
Thompson admitted that the team have to remain focused on the SPL this weekend with the Hampden showdown against Hearts looming next weekend.
"We obviously have the game against Dundee United and have to show a reaction to losing to Dundee during the week, to give belief and confidence back to the supporters for next weekend," he said.
"But there is no doubt you would be lying if you said you weren't thinking of next weekend. It has certainly been at the forefront of my mind for quite some time."
Dundee United could hand a debut to new signing Rory Boulding for the trip to Paisley.
The former Livingston striker has signed until the end of the season as cover after Johnny Russell was ruled out with a fractured leg.
Swedish defender Marcus Tornstrand could also feature with Gavin Gunning ruled out with an injured knee.
The 24-year-old failed to make a first-team appearance at Newcastle before his permanent move to Celtic last year, following two loan deals at the Parkhead club.
However, he has forced his way into the England squad this season, thanks in part to the Hoops' remarkable Champions League campaign which saw them make the last-16 before exiting to Juventus in Turin on Wednesday night.
Forster is one of several players who could be subject to bids from interested clubs in the summer.
Speaking ahead of the Clydesdale Bank Premier League match against Ross County in Dingwall tomorrow, he said: "It is definitely one of my ambitions at some point to play down south, I think it is everyone's ambition at some point to test themselves in the Premier League and we will just have to wait and see if it happens.
"We have an ambitious squad and you can't blame them if they want to go and fulfill ambitions elsewhere.
"For me, it is key to stay in and around the England squad.
"I have got the taste of it. I want to push Joe Hart in the long run but Ben Foster has come our of retirement in the last couple of weeks and he is obviously a fantastic keeper.
"But it is important that I am playing and being tested week-in, week-out."
