PITTSBURGH -- Pittsburgh wide receiver Larry Fitzgerald did not practice Friday, one day after injuring his left hamstring.
Coach Walt Harris said he was not sure when Fitzgerald would return.
"I think it's going to take a while," Harris said. "Obviously, we're going to be intelligent about when he comes back, but we're not sure when."
Fitzgerald, who set several freshman school receiving records last season, spent the entire three-hour practice Friday doing rehab and conditioning for the injury.
"Some guys, you have to push them, but Larry, we're going to have to hold him back," Harris said. "Larry probably thinks he's ready to run right now. Obviously, he's not."
Fitzgerald caught 69 passes for 1,005 yards last season, breaking Antonio Bryant's freshman record of 51 catches for 844 yards. Fitzgerald also became the first Big East freshman to have 1,000 yards receiving in a season.
The 6-foot-3, 225-pound receiver also had 12 touchdowns, breaking Dwight Collins' freshman school record of 10 in 1980.
