We might not know until Tuesday whether Kolb will be healthy enough to participate in upcoming practices, or if the injury will affect his competition with John Skelton for the starting job. The team practices Tuesday afternoon.
The Cardinals' quarterback competition is expected to pick up momentum Sunday in the exhibition opener against New Orleans in Canton, Ohio.
Kolb and the Cardinals were practicing Monday when Kolb absorbed a knee to the thigh. The injury occurred late in practice. Kolb sought treatment and then followed through with plans to sign autographs.
A turf-toe injury and a concussion limited Kolb to seven games last season.
