Various news sources are reporting players that the 49ers may show some interest in this week, whether it be on Thursday, the start of free agency, or sooner for those players that were cut by other teams.

RB DeShaun Foster
ESPN's John Clayton expects the 49ers to sign free agent running back DeShaun Foster "in the next couple of days." San Francisco was quick to contact Foster after he was cut last Thursday. The Niners would reportedly use him as a complement to Frank Gore, but he'd be the biggest threat for carries Gore's faced since Kevan Barlow in '05.

DE Justin Smith
Geoff Hobson of Bengals.com is reporting that the 49ers are negotiating with defensive end Justin Smith.

WR Muhsin Muhammad
According to ESPN, the 49ers are one of three teams that may be interested in acquiring the services of wide receiver Muhsin Muhammad. ESPN states that he "would likely fill the slot in San Francisco, as Mike Martz needs speed and quickness outside." The other teams that may be interested are the Redskins and Panthers and ESPN seems to feel that a spot in Carolina would make the most sense.

WR Javon Walker
According to the Denver Post, the San Francisco 49ers are one of nine teams that are expected to at least inquire about a trade for Denver Broncos wide receiver Javon Walker. The other teams include Tampa Bay, Dallas, Washington, Tennessee, Pittsburgh, Carolina, Chicago and the New York Jets.

LB Lance Briggs
Various rumors that the 49ers are interested in linebacker Lance Briggs. However, the NFL is currently investigating charges that the 49ers tampered last season making overtures to the linebacker.
