The San Francisco 49ers announced on Thursday that they have released cornerback Curtis Holcomb from the team

Holcomb, a seventh-round draft pick last year, missed his rookie season with an Achilles tendon injury, missing even more time this year in training camp with a leg injury.

Holcomb returned to team drills on Wednesday with the 49ers, making a nice play to push Delanie Walker out of bounds at the 1-yard line on a series in the red-zone. Nevertheless, it was not enough to save him.

Holcomb was trying to earn himself a a spot in a cornerback unit that returned its top four players from the 2011-12 season, inlcuding Carlos Rogers, Tarell Brown, Chris Culliver and Tramaine Brock. Perrish Cox has also had a good showing in camp thus far as well. All will be in action in Friday night's preseason opener against the Minnesota Vikings at Candlestick Park.
