MIDDLESBROUGH will be without Yannick Bolasie for an extended period, with the winger having suffered a hamstring injury in training on Thursday.

Bolasie only made his debut in last weekend’s home defeat to Brentford, having joined on a season-long loan from Everton at the end of last month.

However, he was not involved in today’s 2-1 defeat at Derby County, and is set to spend a number of weeks on the sidelines.

Boro boss Neil Warnock said: “Yannick strained a hamstring with the last kick of the training session on Thursday. That’s the way it’s going at the moment, and things aren’t dropping for us either. It’s easy to feel sorry for yourself, but you’ve just got to get on with it.

“I don’t know really know quite how serious it is. I think he’s had a scan, but to be fair, I haven’t asked. I just know he’s out for a while.”

Boro’s injury problems are showing no signs of easing, with Dael Fry and Marcus Tavernier unlikely to be available for Tuesday’s home game with Huddersfield Town.

Warnock said: “I don't think Dael, Tav or Yannick will be available on Tuesday. I'd normally tell you they've got a chance so I didn't give my team away but why worry?

“I knew yesterday that Yannick wouldn't play but I couldn't say anything. It's sods law. It's always your best players.

“At clubs like ours you can't do without three of your best players. Tav almost won the game on his own when we played Derby at our place. It is disappointing for a manager, but you just have to get on with it.”

Today’s defeat saw Boro conceded first-half goals to Lee Gregory and Colin Kazim-Richards before a strike from Neeskens Kebano at the end of the opening period reduced the arrears.

The Teessiders dominated possession throughout the second half, but despite Warnock throwing on Chuba Akpom, Ashley Fletcher and Nathaniel Mendez-Laing, they never seriously threatened David Marshall’s goal.

Warnock said: “Once again, I didn’t think we were a threat. Since I’ve been here, in fact over the last few years, there’s not been enough threat up front.

“I thought last week if we’d had (Ivan) Toney we would have won the game, and I think if we’d had Kazim-Richards today we would have won the game too. I don’t think there’s much wrong that needs putting right, but at the moment, it’s hard to see what we can do.

“We’ve got to come up with answers to score goals. I could have been in either goal today I think and I would probably have got six out of ten.”
