BLACKBURN Rovers full-back Derrick Williams will find out later today the extent of the injury he picked up against his old club Bristol City on Saturday.

The 23-year-old was helped off after 49 minutes at Ashton Gate when he felt his hamstring as he lunged to block a cross.

He was replaced at left-back by Charlie Mulgrew, who is himself coming back from injury.

Manager Owen Coyle said: "Derrick will need to be assessed, but it certainly wasn't great and that is why he had to come out of the game.

"It is his hamstring so we'll have to assess the severity of the injury.

"Hopefully it won't be too long but the medical team will look at him and take it from there.”
