Greg Toler's loss and Cardinals' secondary

Losing Greg Toler for the season with a torn ACL hurts the Arizona Cardinals at a position of strong depth.

Toler, the starter at right cornerback, suffered a non-contact injury when he stepped awkwardly during the team's preseason game against San Diego on Saturday night. Richard Marshall, Patrick Peterson and A.J. Jefferson give the Cardinals three cornerbacks they feel comfortable playing extensively in the regular season.

The team becomes more reliant on Michael Adams recovering from knee surgery in a timely fashion. Adams could return for the regular season. Adams has played extensively as a backup over the last couple of seasons.

Toler's injury means the team will enter the 2011 season with two starting cornerbacks new from last season. The Cardinals traded their other incumbent starter, Dominique Rodgers-Cromartie, to the Philadelphia Eagles as part of the Kevin Kolb deal.

Jefferson has been starting at left corner and has played well. Toler was starting on the right side. The Cardinals drafted Peterson with the expectation that he would move into the lineup, and that will happen at some point. It's a little early to say when.
