Ameer Abdullah's stay on the San Francisco 49ers' active roster was brief as the veteran running back was placed on season-ending injured reserve on Monday after a rib issue sustained in Saturday's preseason opener against the Denver Broncos.

On Monday, running back Jeff Wilson Jr. took part in his first practice since re-signing with the San Francisco 49ers, the team where he began his NFL career.

San Francisco, who has battled numerous injuries on both sides of the ball throughout training camp, will re-sign former running back Jeff Wilson Jr., ESPN’s Adam Schefter reported Sunday, citing Wilson’s agents, Drew Rosenhaus and Shawn O’Dare.
