More backfield woes for Broncos as Pittman, Hall lost to injuries

DENVER -- The Broncos placed running backs Michael Pittman and Andre Hall on injured reserve, depleting an already thin backfield.

Pittman reinjured his neck in a 26-17 loss to Miami on Sunday. He was the team's leading rusher with 320 yards this season.

Hall is out with a left hand injury.

Selvin Young has missed the last three weeks with a groin injury, leaving rookie Ryan Torain as the only relatively healthy running back on the roster.

Torain carried the ball three times for 1 yard Sunday in his first game back since breaking his left elbow in training camp.

Denver also signed defensive tackle Matthias Askew to its practice squad.
