SANTA CLARA, Calif. (AP) -The San Francisco 49ers put right guard Justin Smiley on injured reserve Thursday, one day after the starting lineman decided to undergo season-ending surgery on his right shoulder.
Smiley, who has started every game for the 49ers over the past 2 1/2 years, was hurt while diving to recover a fumble in Sunday's loss at Atlanta. Smiley tore his labrum and severely dislocated his shoulder.
The 49ers replaced Smiley on the 53-man roster by re-signing lineman Patrick Estes, a seventh-round pick in 2005 who has been cut and re-signed twice this season.
David Baas will replace Smiley in the starting lineup, while Adam Snyder will remain the starting left tackle in place of Jonas Jennings, who went on IR on Monday with an ankle injury.
