Wolverhampton Wanderers goalkeeper Wayne Hennessey is a doubt for Saturday's Championship clash with Colchester United after suffering mild concussion during the impressive 2-0 win at Crystal Palace last Saturday.

The Wales international was replaced towards the end of the victory after suffering a head injury following a collision with Palace's Matt Lawrence.

"Wayne never lost consciousness but we took him off to hospital to be checked," Wolves physio Steve Kemp said. "He was caught on the cheekbone but an X-ray showed there was no serious damage.

"He did have mild concussion but was released from hospital and allowed to travel home just before midnight. He was in a bit of pain, though, so we'll monitor him during the week to see how he is."

Meanwhile, manager Mick McCarthy has hailed his goalscoring heroes for firing Wanderers to their first win in five games and keeping their play-off hopes alive.

Full back Michael Gray scored his first league goal since October 2002 and Kevin Kyle added the second. Both goals were 25-yard stunners and came in the final 15 minutes of the game. McCarthy was particularly pleased with Gray's performance.

"He switched sides with Stephen Elliott, cut in with his left foot and hit a screamer," he said. "It's great when they fly in like that.

"I'm really thrilled for Kevin because there were a few boos about the place last week. It means so much to a player to come to a club, do well and be accepted. He's got ability and that volley shows it."

After so many false dawns and after expectations rose to an unrealistic level, McCarthy refused to discuss the prospect of the play-offs. "We just need to take a look at each game individually and let's see where we are at the end of the season when it matters.

"Let's just focus on Colchester next and on trying to get three points there."

Meanwhile, Kyle said the players were determined to perform for McCarthy after letting him down with an abject performance at Cardiff City the previous week.

Wanderers fans hurled abuse at the players following the 2-0 FA Cup defeat and Kyle said the criticism was justified.

"The fans had every right because it was awful," he said. "The gaffer has been getting a lot of stick and on Saturday I think the players had to stand up and be counted for him.

"Instead of the gaffer getting it on the chin it has to be the players out there doing it. We're the ones out on the park.

"I've seen the manager before when he has been getting a bit of stick at Sunderland and he just rides through it, and he gets the best out of players.

"Some of the fans might disagree with his team selections but he sticks with what he believes in and eventually it will come good for everyone.

"We really needed this result and I wasn't disappointed to be on the bench because I know I was poor last week. Hopefully, I've made up for that by helping us get the three points which keeps us in the hunt."
