Stoke City manager Mark Hughes has confirmed that defender Marc Wilson has suffered a "bad knee injury" during their 1-0 FA Cup defeat to Crystal Palace on 30 January. He collapsed holding his knee in the later stages of the game at Selhurst Park and his boss has confirmed the 28-year-old is set to be out for close to three months.

The Potters make a trip to Old Trafford as they face Manchester United in the league tie on 2 February. With Wilson's latest injury setback, Stoke have suffered a massive blow as they are already without the services of star centre-backs Ryan Shawcross and Geoff Cameron due to injuries.

Hughes has seen his side get knocked out of both the Capital One Cup and the FA Cup in less than a week. He is already without the services of two star players and injury to Wilson – who was acting as a cover for Shawcross and Cameron – has forced the former Manchester City manager to look out for a new defender before the end of the January transfer window.

"Marc looks like he's got a bad knee injury. He's got medial ligament damage, the physio thinks, so he's going to be out for a period of 10 to 12 weeks, unfortunately," Hughes said, as quoted by Goal.com.

"The injury might force our hand [in the transfer market] because we are bit threadbare with Ryan Shawcross injured, Geoff Cameron unavailable and Marc Muniesa only just coming back into the team. So we might have to do a short-term thing.

"We didn't want to go out of two cup competitions. We were a bit stretched today with a number of players unavailable. We had a number of players on the bench, but we didn't want to risk the likes of Marc Muniesa and Peter Crouch who played 120 minutes in midweek," he added.

Stoke will not able to call upon midfielder Charlie Adam for the United clash. He has also suffered a calf tear during the second leg of the Capital One Cup clash against Liverpool and Hughes confirmed Adam will out for "a few weeks".

"Charlie has popped his calf and he felt quite a bit of pain. It'll be a few weeks I think," the Stoke manager explained, as reported by ESPN. "Marko has got a couple of bangs in his back which he's been struggling with for a couple of weeks. Hopefully that will settle down and he'll be OK."

The Potters sealed a comfortable 2-0 victory over Louis van Gaal's side at the Britannia Stadium when the two sides faced each other last time during the league tie on Boxing Day. Stoke's latest injury crisis and disappointment of being knocked out of two competitions in last two matches will be a massive blow for them when they face United on Tuesday.
