CHARLOTTE, N.C. -- Panthers coach Ron Rivera says running back DeAngelo Williams is "doubtful" for this weekend's game against the Chicago Bears, the latest setback for Carolina's ground game.

Williams, who had just returned to the Panthers' lineup after missing the last two games with a bad hamstring, suffered an ankle injury during the second quarter of Sunday's game against the Baltimore Ravens.

The loss of Williams further hits at a Panthers roster already thin at the running back position due to injuries.

Carolina now has only two healthy running backs -- undrafted rookie Darrin Reaves, who had 26 yards on 12 carries against the Ravens, and free agent Tauren Poole, who fumbled on his only carry last week.
