Peyton Hillis' season took another hit Sunday when he suffered a pulled left hamstring on his second run of the game and managed only four carries thereafter.
Hillis, who ran six times for 14 yards, will undergo an MRI on Monday to determine the extent of the injury.
"It's all frustrating," said Hillis. "But when it rains it pours and you just kinda roll with the punches. Everything's a life-learned lesson. The more optimistic you are about it, the more positive you can be and have an open mindset about it, the better off you'll be."
