The 49ers reportedly visited Thursday with Seattle free-agent offensive tackle Garry Gilliam, who started 29 games the past two seasons.
Gilliam, 26, is a restricted free agent whom the Seahawks gave a low tender to maintain the right of first refusal. Another team can sign Gilliam to an offer sheet and the Seahawks would have the right to match. If Seattle does not match, the organization would receive no compensation.
Gilliam (6 foot 5, 315 pounds) signed with the Seahawks in 2014 after going undrafted out of Penn State. Gilliam started all 16 games at right tackle in 2015.
