Bradford pair Omar Daley and Steve Williams are doubtful for next Saturday's league clash at manager Peter Taylor's former club Wycombe.
Jamaican winger Daley is currently nursing a hamstring problem and missed Saturday's FA Cup defeat, while defender Williams was withdrawn with a groin strain at Colchester after Taylor had made all three of his substitutions, leaving the Bantams with 10 men in the closing stages.
Taylor said: "We believe he's done something to his groin. He had to come off and he's definitely a doubt for next weekend."
On Daley Taylor added: "He's felt it (the hamstring) in the past. We felt we needed to be careful with it as you can have real problems if one of them goes."
