49ers' Shaun Draughn: May miss preseason finale

Draughn (ribs) may miss Thursday's preseason finale against the Chargers, The Sacramento Bee reports.

Even if Draughn is healthy enough to play, the 49ers would be wise to hold their 28-year-old running back out of Thursday's game, as he's seemingly already locked in as the top backup to Carlos Hyde (concussion). With Hyde making quick progress in the NFL's concussion protocol, the Niners should have their full stable of running backs Week 1 against the Rams. Thursday's preseason game won't be entirely without intrigue, as Mike Davis, DuJuan Harris (and possibly) Kelvin Taylor are duking it out for the No. 3 running back job. Draughn is expected to be fine for Week 1.
