CARLSBAD, Calif. — Former NFL star linebacker Junior Seau drove off a cliff and was hospitalized with minor injuries Monday, less than nine hours after he was arrested on suspicion of domestic violence.

The 12-time Pro Bowler's white Cadillac SUV was found on the beach about 100 feet below the roadside, said Carlsbad police Lt. Kelly Cain. Cain said it wasn't a sheer cliff, but was a significant, rough slope. Seau was taken to Scripps La Jolla Hospital in San Diego.

Seau's 25-year-old live-in girlfriend told authorities that Seau assaulted her during an argument Sunday night at his Oceanside home, according to Oceanside police. She appeared to have minor injuries and did not require medical treatment.

Seau, 41, was arrested outside his home about two hours after police arrived. Seau posted bail and was released from the San Diego County jail in Vista.

Hospital spokeswoman Lisa Ohmstede declined to comment on Seau's condition.

Around the league

Cowboys: The touchdown-celebration penalty Dallas received Sunday wasn't for Miles Austin leapfrogging Roy Williams in the end zone. It was against receiver Sam Hurd for flashing a University of Texas "Hook 'em Horns" hand gesture along with Williams. That's what Carl Johnson, the league's vice president of officiating, told Cowboys Coach Wade Phillips on Monday.

Eagles: Coach Andy Reid said it will be a "real stretch" for receiver DeSean Jackson to play Sunday against Tennessee after suffering a concussion. Jackson had scored both Philadelphia touchdowns to give the Eagles a 14-0 lead at the time of the collision.

Redskins: Coach Mike Shan ahan said Monday there's "a pretty good chance" Albert Haynesworth won't be dealt before Tuesday's trade deadline, even though the two-time All-Pro has missed three of six games and has clashed often with the coach this year. "God, I'll be so glad when that's over with so I don't have to talk about this anymore," Shanahan said.

Lions: Linebacker Zack Follett was cleared to return to Detroit on Monday after being hospitalized for a violent helmet-to-helmet hit with a Giants player. Coach Jim Schwartz said Monday that Follett is "doing a lot better" and that "his tests all came back very, very encouraging." Schwartz also says the injury was not concussion related.

Panthers: Things are so bad on offense for Carolina that struggling rookie Jimmy Clausen was benched Monday to make way for a quarterback with eight turnovers and a 33.3 passer rating. Coach John Fox announced in a team meeting that Matt Moore, benched after six turnovers in the first two games, would again take control of the NFL's worst offense.

Packers: Green Bay Packers will put tight end Jermichael Finley on injured reserve, ending any hopes of him making a comeback from knee surgery later this season. Finley hurt his right knee in the Packers' loss at Washington Oct. 10 and had surgery last week.

Browns: Defensive end Robaire Smith may be out for the season because of a back injury. Smith did not practice last week, and he sat out Cleveland's game on Sunday in Pittsburgh. On Monday, Coach Eric Mangini confirmed that Smith's injury could be long term.
