HOUSTON — Texans coach Gary Kubiak is optimistic Arian Foster will be ready for the regular-season opener after the star running back re-aggravated a hamstring injury in Saturday's preseason game in San Francisco.
Foster, the NFL's leading rusher in 2010, left the field in the first quarter of Houston's 30-7 victory, favoring the left hamstring that he strained early in training camp.
Foster sat out Houston's preseason opener, then rushed five times for 47 yards and two touchdowns in a 27-14 win over New Orleans on Aug. 20. He was hurt on his eighth carry against the 49ers.
"Looks like we're dealing with the same thing we were dealing with at the start of camp," Kubiak said Sunday. "Hopefully, we can get him back on the rehab train, and get him ready for opening day. He'll be day to day."
Kubiak said the trainer offered a "very positive" outlook for Foster's recovery, though the coach stopped short of saying Foster would definitely be healed in time for the Sept. 11 opener against the Colts.
"Until he hops back out there, there's a concern," Kubiak said. "But it sounds like we're heading in the right direction."
Bears: Backup tight end Desmond Clark indicated the left knee injury he suffered Saturday wasn't as bad as it appeared to be, posting on Twitter that he's confident he will return soon. There was no formal update from the team on Clark or running back Marion Barber, who left with a calf injury in the first half.
Bengals: Linebacker Rey Maualuga will move from outside to middle linebacker, where he can play to his strength as a run stopper.
Browns: Receiver Mohamed Massaquoi finally put on a helmet and pads, and caught passes during a noncontact drill, his first football-related action since coming to camp with his left foot in a cast. "It was a bone chip, but I'm not sure when or where it came from," Massaquoi said, though he likely got hurt during a series of workouts led by quarterback Colt McCoy during the NFL lockout.
49ers: First-year coach Jim Harbaugh has concerns about his offense as a whole and the shaky line play two weeks ahead of the Sept. 11 season opener against Seattle. San Francisco gave up three sacks in a loss to Houston on Saturday, prompting Harbaugh to say the 49ers got "violated at times." Without reliable protection, starter Alex Smith had a 2.8 QB rating, and backup Colin Kaepernick had a 20.8.
Raiders: Rookie quarterback Terrelle Pryor, who suited up Sunday against the Saints, is expected to play Thursday in the preseason finale against the Seahawks, according to Profootballtalk.com. Pryor, who will serve a five-game suspension after the preseason ends, is expected to remain a quarterback for now. He was chosen in the supplemental draft but commissioner Roger Goodell ruled that the former Ohio State player undermined "the integrity of the eligibility rules for the NFL draft."
Game highlights: Drew Brees completed 15 of 23 passes for 189 yards and led New Orleans to scores on all three drives he played in a 40-20 win over the host Raiders.
