There were questions about running back Beanie Wells' durability at Ohio State, a major reason he lasted until the Cardinals took him with the 31st pick in the draft in April.
Fair or not, the right ankle injury suffered by Wells in his first practice Saturday at training camp only strengthens the concern. Wells is expected to miss at least a few days of practice this week after suffering the injury during a running play Saturday.
An MRI taken Saturday revealed the sprain, and the Cardinals aren't putting a timeline on Wells' return. The injury is a setback in Wells' quest to take the starting job from Tim Hightower, who has looked sharp in camp.
