49ers place RB Shaun Draughn on IR, claim TE Je'Ron Hamm

SANTA CLARA, Calif. -- Shaun Draughn, who was signed off the street by the San Francisco 49ers to shore up their injury-racked running back corps on Nov. 2, was placed on season-ending injured reserve Wednesday after missing last week’s game with the knee injury he suffered against the Bengals on Dec. 20.

The 49ers also claimed tight end Je’Ron Hamm off waivers from the Redskins in a corresponding roster move.

Draughn started all six games he played as a replacement for Carlos Hyde and Reggie Bush, both also on IR. Draughn averaged 3.5 yards per rush on 76 carries, gaining 263 yards and a touchdown.

He also caught 25 passes for 175 yards.

The 6-feet-3, 236-pound Hamm was an undrafted free agent out of Louisiana-Monroe signed by the Saints in 2014, and had been on the Redskins' practice squad until making his NFL debut against the Cowboys on Dec. 7. He was inactive for four games and waived Tuesday.
