Quarterback Seneca Wallace signed with the San Francisco 49ers, who waived wide receiver Ricardo Lockette.
Wallace was released by New Orleans earlier this week. The nine-year veteran was released before last season by the Cleveland Browns after playing the previous two seasons with the team. He hasn't taken a snap in a regular-season game since 2011.
Wallace, 33, is a Sacramento native who joins the mix behind starter Colin Kaepernick. Colt McCoy was acquired from Cleveland over the offseason and is currently competing with Scott Tolzien and versatile rookie B.J. Daniels. McCoy and Tolzien have struggled during the preseason, and the team is expected to keep Daniels as the third quarterback or on the practice squad.
Lockette signed with the 49ers' practice squad last September and spent the remainder of the season there.
--Safety Darcel McBath was placed on injured reserve. He was second on the team with 649 special teams production points last season. McBath suffered a foot injury in last week's preseason game against Kansas City.
--Linebacker Joe Holland was claimed by the 49ers off waivers from the Tampa Bay Buccaneers. He signed with San Francisco as an undrafted rookie last year, but was waived before the start of the 2012 season and signed with the Bucs in January.
