Bad news for the Cleveland Browns and, more specifically, Peyton Hillis. After returning to practice with the rest of the team on Thursday, Hillis went out on Friday to do the same thing, but apparently re-injured his hamstring and showed immediate frustration, according to Mary Kay Cabot:
#browns rb Peyton Hillis re-injured his hamstring on a run, threw the ball, threw his helmet.
That's pretty bad news, at this point. Last week, Peyton Hillis did some running and things of that nature on Wednesday leading up to the game against the 49ers, but on Thursday, he experienced tightness in his hamstring and was eventually ruled out for that week's game.
It's unclear to what extend Hillis has apparently re-injured his hamstring, but one can assume it has tightened up considerably and that he probably won't be ready for Sunday's game against the Houston Texans. There should be an official injury report on the matter later today.
