SANTA CLARA – The 49ers on Monday announced the signings of veteran linebacker LaRoy Reyonds and rookie running back Austin Walter.

The club waived defensive lineman Ryan Delaire to make room on the 90-man roster for both players.

The 49ers signed Walter to a three-year contract after he impressed the organization with his work during the team’s rookie camp. Walter, who played four seasons at Rice, attended the camp on a tryout basis.

Reynolds, 28, entered the NFL in 2013 as an undrafted rookie with the Jacksonville Jaguars. He has also played for Chicago, Atlanta and Philadelphia during his six-year career.

Reynolds (6-foot-1, 240 pounds) last season appeared in 16 games and was second on the Eagles with nine special-teams tackles.
