Derrick Williams’ foot injury could rule him out until the international break.

Williams has missed Rovers’ last three matches with the injury, with Amari’i Bell deputising at left-back.

The Republic of Ireland will miss Wednesday's visit of Reading, and is also doubtful for Saturday’s game with Brentford and the trip to former club Bristol City on September 2.

Williams will hope to be fit in time for selection for Martin O’Neill’s squad ahead of Ireland’s friendly with Poland on September 11.

The full-back made his debut in the friendly with France in May and has been a mainstay under Tony Mowbray until his recent injury.

“We have staff meetings every day and Derrick is unavailable once again,” Mowbray said.

“I have suffered the injury Derrick has at the moment at the sole of his foot.

“I’m pretty sure it’s nothing to concern us, he just needs to take some of the heat out of it and let it settle down.

“Maybe before the international break but if not the international break will come along and he’ll be ready after that.

“Knowing Derrick he will want to make himself available for the weekend.”

Bell, a January signing from Fleetwood Town, looks set to continue at left-back and will make his ninth Rovers start against Reading.

That will be the first time he has started four consecutive matches for the club.
