Ekeler (neck/concussion) didn't participate in Tuesday's practice.

After suffering a bruised nerve in his neck on an onside kick recovery attempt late in Sunday's 26-21 win over the Bengals, Ekeler entered the concussion protocol after developing symptoms of a head injury during Monday's team walkthrough. Per Sam Fortier of The Athletic, the two injuries make it unlikely Ekeler will rally in time for Thursday's game in Kansas City, potentially leaving the Chargers perilously thin in the backfield. On a more fortunate note, workhorse Melvin Gordon (knee) returned to practice Tuesday in a limited fashion and is angling to return from a two-game absence, but if he can't gain clearance to play, seventh-round rookie Justin Jackson and undrafted free agent Detrez Newsome would be the lone available backs for Los Angeles.
