Midfielder stretchered off after Evans challenge
Owen Coyle is hoping an injury suffered by Stuart Holden against Manchester United is not as bad as first feared.
The Bolton boss saw the midfielder stretchered off during a 1-0 defeat to the Red Devils on Saturday.
Jonny Evans saw red for the challenge, which left Holden writhing in agony and his team-mates screaming for medical assistance.
The United States international was taken straight to hospital after being helped from the field and Coyle is now sweating on the full extent of the problem.
"He's on his way to hospital," he said on Holden.
"The initial concern was that the knee was open. Hopefully it's a cut and no more than that.
"It might need a few stitches but hopefully there's no break or ligament damage. We won't know that until we get word back from the hospital.
"Hope is the right word at the moment. If it was ligament damage he would be missing for a long period of time. We need our central midfielders."
Coyle refused to condemn Evans for the part he played in the injury, with it unclear whether the United defender went in looking to take man and ball.
"I have only seen it in real time and it looked like two players who were fully committed," said the Bolton boss.
"Was there any malice in it? I don't know. The referee was well-placed to call it and he obviously felt there was something in it."
On the game itself, Coyle was disappointed to have seen a point slip through his grasp.
Dimitar Berbatov pounced two minutes from time to see United home, when they were down to 10 men, and the Trotters appreciate that they must learn how to handle such a situation.
"You never think you have done the job regardless of who you are playing, never mind it being Manchester United," said Coyle when asked if he felt a point was in the bag as time ticked down.
"I said before that Stuart was a big loss, but the longer the game goes on, the more nervy players get. They start thinking they are only two minutes away from a draw.
"We tried to win the game and had a great chance with Matty Taylor's header, but they have world-class ability and a desire to keep winning games and championships.
"For us there were loads of positives, but there were also plenty of things we can improve on and move forward as a group.
"It was a great opportunity for us to get a point today, so the learning curve for us is making sure we get one the next time we are in that position."
