San Francisco 49ers defensive tackle Justin Smith will undergo surgery on his injured triceps this week and will need three months of rehab, Comcast SportsNet Bay Area's Matt Maiocco reported Monday.

Smith missed the 49ers' final two regular-season games after suffering about a 50 percent tear in his left triceps during a Dec. 16 game against the New England Patriots. He was able to play in all three of the 49ers' postseason games, including Sunday's 34-31 Super Bowl loss to the Baltimore Ravens. He had three tackles in Sunday's Super Bowl and 11 tackles throughout postseason play.

Smith, 33, has one year and $8 million remaining on his contract with the 49ers. Three months of rehab would put him on track to end by mid-May, and Maiocco reported that he would be ready to return by training camp in July.
