CHICAGO - To say it wasn't the greatest night for the NFC North-leading Chicago Bears would be an understatement.

Not only did the Bears lose their second game of the season to the Houston Texans 13-6, but starting QB Jay Cutler was lost to a concussion.

He was among three high-profile starters lost to their teams Sunday after suffering concussions.

Cutler was scrambling when hetook a helmet-to-helmet hit from Tim Dobbins after unleashing a pass on third down at midfield late in the first half Sunday night.

There were offsetting penalties on the play. Cutler got called for an illegal forward pass because he was beyond the line of scrimmage and then got drilled by Dobbins, who was called for unnecessary roughness.

Cutler stayed in for the rest of the half, but Jason Campbell came out to start the third quarter.

In Philadelphia, Eagles coach Andy Reid says Michael Vick suffered a "pretty significant' concussion and told the quarterback to stay home Monday and rest.

Reid says he could not immediately rule out Vick for Sunday's game at Washington but made it sound likely that rookie Nick Foles will get the start.

Foles will take the first-team snaps when the Eagles return to practice on Wednesday. Foles was 22 of 32 for 219 yards with a touchdown and an interception after taking over for Vick in the second quarter of Philadelphia's loss to Dallas on Sunday.

Reid says Vick complained of a headache and fatigue on Monday. Reid says Vick is still the starting QB but left the door open for Foles to win the job.

And to round out Sunday's QB concussion list, Alex Smithwas knocked outof the San Francisco 49ers' game against the St. Louis Rams after suffering a first-half concussion.

Smith scrambled and started to slide before turning his back late, and linebacker Jo-Lonn Dunbar barreled into his neck area with 1:10 left in the first quarter Sunday. Smith briefly grabbed his facemask and grimaced but stayed in the game, throwing a 14-yard touchdown pass to Michael Crabtree in the second quarter.

Colin Kaepernick replaced Smith on San Francisco's next possession. Smith sat on the bench next to 49ers athletic trainer Jeff Ferguson and other trainers before walking to the locker room just before halftime.

Smith was 7 for 8 for 72 yards anda touchdown when he was forced from the game. The 2005 No. 1 overall draft pick started every game for the 49ers last season.
