PITTSFORD, N.Y. -- Buffalo Bills rookie wide receiver David Nelson is out indefinitely after being carted off the field with a right leg injury during Tuesday's practice.
"It doesn't look good," said Bills coach Chan Gailey, who didn't provide specifics on Nelson's injury.
Nelson was hurt about an hour into practice Tuesday while participating in a team red-zone drill. He caught a Levi Brown pass over the middle, turned toward the end zone and was on his way down when he was nudged sideways by a defender, who was attempting to avoid a collision.
It appeared that Nelson's right foot was caught in the turf as he fell.
Nelson immediately clutched at his lower leg. Trainers spent about five minutes treating the player and keeping his foot elevated. Nelson was then loaded into a cart and unable to put any weight on his foot.
An undrafted rookie free agent out of Florida, Nelson is part of a raw and inexperienced receiving corps competing for a backup spot on the team. He had a solid NFL debut, making a team-high five catches for 47 yards and one touchdown during a 42-17 loss Friday at Washington in the Bills' preseason opener.
Buffalo already is down two receivers entering its preseason game Thursday against the Indianapolis Colts in Toronto. Rookie Marcus Easley is set to have surgery on his left knee, and James Hardy has missed a week with an undisclosed injury.
And that doesn't include Felton Huggins, who was waived/injured last week after he hurt his left shoulder.
Starting free safety Jairus Byrd missed practice Tuesday because of what Gailey called a "physical complication." Gailey provided no other details except to say he believes it will be resolved very quickly and that the player was having the complication checked out.
