Memphis football running back Greg Desrosiers will miss "a couple weeks," coach Ryan Silverfield said.

"I think Greg's probably out for a couple weeks, unfortunately," Silverfield said Saturday after Memphis (3-1, 0-1 American Athletic Conference) lost 56-44 at Navy. "I look at it one game at a time. But we'll reevaluate things in a couple weeks."

Desrosiers took a big hit during last week's win over Florida State and did not play against Navy. The CBS Sports broadcast reported that he was out with a "clavicle injury."

A transfer from UMass, Desrosiers took on a significant role in Memphis' offense after starting running back Sutton Smith suffered a season-ending knee injury in the opener against North Alabama. Desrosiers' ability as a change-of-pace back meant he saw a lot of the plays that would have gone to Smith, and he also served as Memphis' kick returner.

Desrosiers scored a receiving touchdown in the win over the Seminoles. He has 16 carries for 95 yards and a touchdown this season.

With Desrosiers and Smith out, Memphis had to get creative in the backfield. Mario Anderson and Brandon Thomas each got a significant amount of work against the Midshipmen, and both rushed for over 100 yards. Wide receiver Ja'Koby Banks also lined up in the backfield and got a carry.
