--TE Billy Bajema, at the $927,000 salary he made last season, might be getting a little too expensive to retain as a blocking specialist.

--OT Damane Duckett spent the season on injured reserve because of an August knee injury. He spent the entire season rehabbing at the team's facility, which would seem to indicate the club wants to keep him around.

--DT Ronald Fields did not get a whole lot of action behind starter Aubrayo Franklin. He will likely have an opportunity see what he can get on the open market.

--RB DeShaun Foster languished on the sideline for most of the season as Frank Gore's backup. Showed his worth when pressed into action, but the 49ers might be looking to get younger at the backup spot.

--DE Roderick Green had a disappointing season as the third-down pass rusher. Team will be looking to upgrade.

--WR Bryant Johnson was the second-leading receiver with 45 catches for 546 yards, but youngster Josh Morgan is penciled in as the starter at split end.

--QB Jamie Martin is 39 and will not be back.

--QB J.T. O'Sullivan was favorite of Mike Martz, but Martz is no longer around. O'Sullivan's propensity for turnovers led to his benching after eight games. He likely will not return.

--KR
Allen Rossum did a nice job on kickoff and punt returns. The club could look to get younger here, though.

--TE Sean Ryan signed late in season as an H-back/fullback type. He is a low-priority re-signing.

--LB Takeo Spikes ranked second on the team with 122 tackles. He wants to be back, and the 49ers liked his influence on Patrick Willis. The sides should be able to reach a deal.

--CB Donald Strickland is a versatile defensive back, who has done everything asked of him. He should be back on the team.
