Here is an updated list of the roster moves that the 49ers have made during free agency so far and the players that the team may be interested in. This listing will be updated throughout the day.

The big news right now is defensive end Justin Smith's visit to the 49ers today.

Signed

DE Justin Smith (Bengals - 6-yr, $45 mil)
WR Isaac Bruce (Rams - 2-yr, $6 mil)
CB Allen Rossum (Steelers - 1-yr, $870,000)
LB Dontarrious Thomas (Vikings - 2-yr)

Smith visited with the 49ers on Friday and finally signed with the team. After being unable to come to an agreement on a new contract in St. Louis, Bruce was cut by the Rams. 49ers offensive coordinator Mike Martz is very familiar with Bruce and likely influenced the decision to go after him. Bruce is 35 years old. He was signed on Friday. Rossum will serve as the team's kick-returner. Not a good sign for WR Michael Lewis and RB Maurice Hicks. Thomas is an interesting signing. Some believe that he will replace Derek Smith, who was released by the team, while others believe that he was signed for depth.

Agreed to terms

RB DeShaun Foster (cut by the Panthers - 2-yr / $1.8 mil)
QB J.T. O'Sullivan (Lions - 1-yr / NFL min w/ $40,000 signing bonus)

Foster will help shoulder the load behind running back Frank Gore. O'Sullivan will serve as the 49ers' third quarterback as Alex Smith and Shaun Hill compete for the starting job.

Confirmed Interest

DE Marques Douglas (49ers)

The 49ers are interested in bringing back Douglas, but are willing to risk letting him test free agency.

Out of the Running

G Alan Faneca (Steelers - signed by Jets)
LB Lance Briggs (Bears)
WR Muhsin Muhammad (Bears - signed by Panthers)
