The San Francisco 49ers signed their fourth-round draft pick, center Cody Wallace, the team announced yesterday on its Web site.

Terms of the contract were not announced by the team.

The 6-foot-4, 300-pound Wallace was the 107th overall pick out of Texas A&M. He served as the team captain last year and started 13 games, earning All-Big Twelve Conference and league's Co-Offensive Lineman of the Year honors.

Wallace's signing leaves the 49ers with first-round pick defensive tackle Kentwan Balmer as the last of the six 2008 draft picks to sign with the team. Defensive back Reggie Smith, the team's third-round pick, signed Tuesday.
