Tony Mowbray believes Ryan Nyambe’s desire and workrate can prove detrimental, and goes some way explain his run of hamstring injuries.

Nyambe was forced off in the 1-1 draw with Preston at the weekend having just returned from hamstring strain picked up in the Boxing Day game with Birmingham City.

The 22-year-old also had two injury absences last season, and has missed seven games already this campaign.

It is a concern for boss Mowbray, with Nyambe having impressed in the first half of the game with North End in which he was a constant threat down the right-hand side.

The Namibia international had trained for two days in the lead up to the game, having missed the previous three matches, with Mowbray now waiting for news on his latest hamstring injury.

“Nyambe was a loss because first half I thought he was a massive threat to them down our right,” Mowbray said of the right back who has started 13 Championship games this season.

“Allay that to (Bradley) Dack and (Corry) Evans, it’s not easy for us. But they are fighting and showing they are giving everything for the club.

“He misses games but because he’s so conscientious he comes back and runs so hard, so fast and the workload and effort is probably detrimental to his own body.

“I hope it’s just a cramping up. He’s a young guy who doesn’t really know his body.

“He’s driving himself every game to his maximum and hopefully it will settle down and by the end of the week we can get him back on the training pitch.

“Defensively we looked a lot more solid, and if we can working on that, get it right, get Nyambe back hopefully for next week.

“Hopefully it’s just a cramping up, a strain, because I thought the team solid and hungry to win and fighting to win.”

Elliott Bennett replaced Nyambe early in the second half, the captain himself having shaken off an Achilles injury that saw him replaced in the FA Cup defeat at Birmingham City seven days earlier to feature.

Rovers have had injury problems at the back this season, with left back Greg Cunningham ruled out for the remainder of the campaign and will return to parent club Cardiff City this month.

Derrick Williams is also just back from a calf problem, his second of the season, having returned after two months out to replaced Bennett at St Andrew’s.
