The 49ers on Monday worked out offensive tackle Jason Smith, the no. 2 overall pick in the draft by the Rams in 2009, according to a league source. Smith (6-5, 308) dealt with injuries - most significant, concussions - while with the Rams, and in 2012 he was traded to the Jets. Since then he has been released by the Jets twice and the Saints once.
The 49ers, meanwhile, have depth on the interior of their offensive line in Adam Snyder, Daniel Kilgore and Joe Looney, but do not have any reserves who are primarily tackles. Two of their practice-squad players, seventh-round draft pick Carter Bykowski and undrafted rookie Patrick Omameh are tackles.
If either of the team's starters, Joe Staley or Anthony Davis, had to leave a game, the 49ers could replace them with Snyder or with right guard Alex Boone, who began his career as a tackle. Davis was observed getting X-rays after Sunday's win over Green Bay. Davis did not miss any plays Sunday and did not have any obvious injuries.
According to ESPN, the 49ers also inquired about quarterback Brady Quinn, a free agent last week who eventually signed with the Jets. Quinn wanted guarantees in the contract that San Francisco was not willing to provide, Chris Mortensen reported. Quinn spent the summer with the Seahawks, the team the 49ers face on Sunday. Another quarterback, John Skelton, also has worked out for the 49ers recently.
