HARRY Chapman is to undergo surgery on a hamstring injury which is set to rule him out for up to three months.

The winger picked up the injury in the second half of last weekend’s 0-0 draw at Wigan and Tony Mowbray confirmed the Middlesbrough loanee is set for an extended spell out of the side.

When asked for an update on the 19-year-old, Mowbray said: “It’s not good news.

“He’s got quite a severe hamstring injury, it’s not a basic hamstring injury.

“I don’t know the definitive answer (of how long he’ll be out) but it could be maybe three months.

“We have to put Harry to the back of our minds.

“It’s a shame for the boy, a shame for us because he was just starting to come to the party after dipping him in, and then he starts and we get a 3-0 victory with Chapman in the team.

“For it to a happen is a blow for us because of the type of player he is, the individuality he brings, but the main concern is for Harry.

“He’s a young boy who could do without a hamstring injury but having spoken to the head of medical at Middlesbrough and obviously our medical department he will be given every care to get himself fit and back here in a good few weeks, but hopefully back to help us get over the line towards the end.”
