TEMPE, Ariz. -- Arizona Cardinals quarterback John Skelton has a low ankle sprain.
Coach Ken Whisenhunt called the diagnosis "good news," considering Skelton had to be carted off the field in the fourth quarter of Sunday's 20-16 victory over Seattle.
Tests were negative for a fracture and initial concerns were that it would be a more serious high ankle sprain.
Whisenhunt would not speculate on how long Skelton would be sidelined.
Kevin Kolb replaced Skelton and led the team on the winning touchdown drive. Arizona plays at New England next Sunday.
