Adam Caplan of FOXSports.com reports the San Francisco 49ers have agreed to terms with outside linebacker Bruce Davis.

Davis would take the roster spot of cornerback/return specialist LeRoy Vann, who was waived on Monday.

A 2008 third-round pick (88th overall) out of UCLA by the Pittsburgh Steelers, the 6-3, 252-pound linebacker appeared in five games as a rookie, but was not add his name to the stat sheet.

Waived by the Steelers at the end of the 2009 training camp, Davis was signed to the Patriots' practice squad in October, where he'd remain for the rest of the '09 season. Davis signed a "Reserve/Futures" contract with New England in January, and was waived along with wide receiver Isaiah Stanback at the end of May when the Patriots signed linebacker Derrick Burgess.

Davis was claimed by the Denver Broncos, who waived him on July 27 when the club signed a pair of 2010 NFL Draft picks.
