The 49ers signed seven players to their practice squad Sunday, including former Stanford linebackers Shane Skov and Chase Thomas.
Others were offensive tackle Carter Bykowski, wide receiver Lance Lewis, tight end Asante Cleveland, defensive lineman Lawrence Okoye, and nose tackle Mike Purcell.
All seven were cut by the 49ers on Saturday, and they cleared waivers.
Teams are permitted to sign as many as 10 players to their practice squad. Those players don't count against a team's 53-man roster.
Also, running back Glenn Winston and guard Ryan Seymour, cut by the 49ers on Saturday, were claimed off waivers by the Cleveland Browns
