Stoke City manager Tony Pulis is waiting to learn the extent of the Achilles tendon injury suffered by Ricardo Fuller in the 1-1 draw at Aston Villa.
Fuller was introduced as a 75th minute substitute at Villa Park, but the striker was stretchered off before the full-time whistle.
With Stoke having an FA Cup final on the horizon, there are fears Fuller will not be fit for the Wembley encounter with Manchester City.
"It's his Achilles that he has damaged and, although it is too early to say, it does not look too good," said Pulis.
"It is a big blow to us because he is a game changer who can come on and do special things.
"Even in the short time that he was on the pitch today, he created three or four opportunities out of nothing. That is Ric for you."
Delighted with point
Kenwyne Jones' header had given Stoke the lead before Darren Bent's goal just before half-time drew Villa level.
Pulis added: "The worst thing that happened to us was half-time. We looked bright in the first 40 minutes and, but for an unbelievable save from Friedel, we might have been further in front at that stage.
"But you only have to give Bent half a chance and he punishes you, and at half-time, I could see one or two were a bit jaded when we got in the dressing room at half-time.
"We couldn't get going after the break and it was really just a matter of trying to stay solid so that we hung in there.
"I am delighted with the point because Villa have been on a good run and this was always going to be a tough game.
"Our brief over the past three years has been to stay in this League and we still need points to ensure that is the case.
"It has been quite remarkable what we have achieved in reaching the FA Cup final, but there is no danger of us letting that affect our main priority, and I think that showed in the way we performed in the first half today."
