Bolton boss Owen Coyle is resigned to Sam Ricketts being out for a lengthy period of time after the defender was injured in the FA Cup fourth-round replay win at Wigan. Coyle, who expects Zat Knight to be out for four to six weeks after the centre-back sustained an ankle ligament injury in Sunday's win over Everton, confirmed Ricketts had an Achilles problem and is likely to be sidelined for some considerable time.
Coyle said: "He has damaged his Achilles and it doesn't look great at this time.
"The medical team think it could be quite severe and we hope that is not the scenario, but the way it is looking right now, I think it is going to be a lengthy period of time.
"I think he just went to recover as Moses was raiding for Wigan, and it looked innocuous, but because of the speed the game is played at - he has certainly damaged his Achilles, that is for sure.
"I just need to find out the extent of it tomorrow when it is looked at properly."
