Golston (hamstring) visited with the 49ers on Friday, Matt Barrows of The Sacramento Bee reports.
Golston, who opened the 2016 season as the Redskins' starting nose tackle but suffered a season-ending hamstring tear in Week 2, was medically cleared from the injury roughly two and a half weeks ago. This meeting with San Francisco marks the first free-agent visit of the offseason for the 33-year-old vet. The 49ers are beginning to construct a fearsome defensive line and Golston would, at the minimum, provide excellent depth and a strong veteran presence.
