The 49ers announced today that they placed NT Glenn Dorsey on the injured reserve/designated for return list on Tuesday afternoon. It was the first day that all NFL teams are allowed to use the injured reserve/designated for return list.
Dorsey injured his biceps in training camp last August, leaving him out for a significant amount of the season. Last year, he was the team's starting nose tackle after Week 2 as incumbent Ian Williams was out for the season with an ankle injury.
Osgood, 34, is a three-time Pro Bowler known for his abilities on special teams. He can play on any kicking coverage or return unit if needed. This is the second straight year where Osgood did not make the initial 53-man roster, but was re-signed later.
Teams who put a player on the injured reserve/designated for return list cannot activate him until after eight weeks have passed. Dorsey will not be eligible to practice with the team until Week 6. This list can only be used once as last year the 49ers put Nick Moody on the list after a Week 1 hand injury.
Dorsey will be on track to return in late November or early December as he recovers from a biceps injury that will sideline him 3-4 months. Reserves behind Ian Williams on the depth chart at NT include 2013 fifth-round draft pick Quinton Dial and Tony Jerod-Eddie.
