Preston boss Simon Grayson was quick to allay fears over Stuart Beavon after the Lilywhites forward was knocked unconscious during a feisty goalless stalemate with Leyton Orient.

Beavon was stretchered off after 20 minutes following a clash of heads with Orient defender Nathan Clarke that prompted a lengthy stop in play, but Grayson confirmed Beavon was up and about soon after.

Without Beavon leading the line, Preston could not find a way past inspired Orient goalkeeper Jamie Jones, who produced a string of fine saves to deny Jack King twice and Nicky Wroe late on.

Orient rarely threatened and as a result saw their three-match winning run come to an end, while Grayson was left frustrated his side could not collect a third win on the bounce at Deepdale.

"Beavon got a knock to the head, I think he was knocked out for a small period, but he came round and watched part of the second half," said Grayson. "We'll assess him over the next few days, he seems to be okay.

"I suppose it looked worse with the brace, but when somebody's knocked out you don't know what could happen, but we went in at half-time and he was having a shower.

"Through good defending, being brave, and us being not as clinical as we should be, we weren't up a couple of goals at half-time. We've taken another point, kept another clean sheet, and drawn a game we could have easily won."

In failing to keep their winning run going Orient lost ground in their push for a play-off place and currently sit ninth, three points behind Yeovil in sixth, but assistant manager Kevin Nugent believes it was a point earned after his side's rearguard action ground out a result.

"We're happy to get a point after not being at out best really, but we dug the result out in difficult conditions," Nugent said. "Nathan Clarke and Jamie Jones were excellent, if it wasn't for them we would've gone in a few goals down at half-time.

"Nathan Clarke was spot-on, immaculate with his whole performance."
