The 49ers placed safety Eric Reid on their injured-reserve list Tuesday, two days after Reid suffered a season-ending injury.
Reid will have surgery to repair a torn bicep. He had one interception, one forced fumble and four pass breakups in 10 starts this season.
Safety Vinnie Sunseri was promoted from the practice squad to replace Reid on the active roster. He was a fifth-round pick of the Saints in 2014 and went to camp with the Patriots last summer after being cut by the Saints last spring. He played in nine games as a rookie and missed all of last season due to injury.
Sunseri was released from the Patriots’ practice squad in late October and joined the 49ers’ practice squad on Nov. 1.
