Is this something to not be concerned about or a sign of things to come?
Just an FYI...denverpost.com
Midway through the fourth quarter, the Broncos had their scariest moment of the day. On a run around right end, Broncos running back Clinton Portis went down and stayed down, reaching for his foot.
Broncos trainers came to his aid. Portis was able to walk off the field under his own power, but he did not return to the game.
Portis said another player stepped on his foot and it went numb. Shanahan said he has no doubt Portis will be all right.
"I just know how tough he is," Shanahan said. "It might be a little setback, but I'd be surprised at anything that can keep this guy down. Whatever his weight is, he plays about 40 pounds heavier. It would surprise me if he is knocked out of a game or even practice, the way he's prepared and the way he's hung in there."
