IRVING -- Cowboys wide receiver Dez Bryant missed practice on Thursday.
Bryant has an sprained ankle.
Several Cowboys players who missed practice on Wednesday, mainly as a precaution, are expected to participate today.
Defensive end Igor Olshansky (right hamstring) said he's fine and will return to practice. Olshansky's MRI is also clean, his knee bothered him a little bit and he said it's part of the aches and pains of playing in the NFL.
Safety Alan Ball (shoulder) said he will practice on Thursday and won't wear a harness to protect himself.
