Brieda has agreed to a deal with the 49ers, Jeremy Fowler of ESPN.com reports.
Breida spent his first three seasons in San Francisco before stints with Miami, Buffalo and the Giants. His most productive years were those he spent with the 49ers, and he will now look for another opportunity to showcase his talents in the Bay Area. Isaac Guerendo (hamstring) was selected by the team in the fourth round of this year's draft and was expected to back up Christian McCaffrey and Elijah Mitchell in the backfield, but he is now expected to be sidelined for multiple weeks. As a result, Breida will compete with the likes of Jordan Mason, Patrick Taylor and Cody Schrader for a depth running back role heading into the season.
