Who Should I Start? Ameer Abdullah or Corey Kiner

Monday, August 11, 8:41 PM

The San Francisco 49ers have placed running back Ameer Abdullah (ribs) on season-ending injured reserve, according to ESPN's Adam Schefter. Abdullah, who just joined the 49ers as a free agent on July 31, suffered a rib injury in a preseason-opening 30-9 loss to the Denver Broncos this past Saturday. While the 32-year-old was unlikely to make much of an impact this season (if any), it's another hit to San Francisco's depth in the backfield. The team is already set to go multiple weeks without injured Christian McCaffrey backups Isaac Guerendo (shoulder) and Jordan James (finger). The 49ers brought back Jeff Wilson Jr. in free agency on Sunday in the wake of Abdullah's injury to provide some much-needed healthy depth behind McCaffrey.

Rookie Corey Kiner had a solid day in his professional debut. In the 49ers' preseason opener against the Denver Broncos, Kiner led San Francisco's backfield in touches and yards, taking 10 carries for 45 yards and catching one pass for a two-yard gain. He also served as a kick returner, bringing one back for 17 yards. Kiner, an undrafted free agent, comes to the 49ers after back-to-back 1,000-yard seasons as a Cincinnati Bearcat and figures to see a lot of work in the preseason. San Francisco is unlikely to put Christian McCaffrey's health on the line so early, and Isaac Guerendo (shoulder) and fellow rookie Jordan James (finger) are set to miss multiple weeks while nursing injuries. Kiner will have his next chance to impress next week against the Las Vegas Raiders.
