The 49ers signed Dillard (concussion) on Friday, Jennifer Lee Chan of NBC Sports Bay Area reports.
Dillard was unable to suit up for the Packers' NFC wild-card loss to the Eagles due to a concussion, but his signing with the 49ers on Friday suggests he's since moved past the issue. Now in San Francisco, Dillard is expected to compete for a depth spot on the team's offensive line throughout the summer.
