Arizona running back Beanie Wells went through much more of practice on Thursday, increasing the probability that he will play Sunday in the Cardinals' home opener against the Oakland Raiders.

Wells, who led the team in rushing as a rookie last season, sat out the first two games of the season because of a bruised right knee.

Coach Ken Whisenhunt said Wells looked "really good" in practice. The coach said he is "very optimistic" Wells will play.

Wells said he is tremendously improved from last week and is practicing full speed, not even thinking about the injury.
