Rookie quarterback Philip Rivers ended his lengthy holdout, agreeing to terms on a six-year contract with the San Diego Chargers.

The contract will pay Rivers $40.5 million, including a $14.25 million signing bonus. He can earn $10 million more in incentives.

Chargers general manager A.J. Smith said Rivers was driving to the team's training camp from San Diego Monday night and was expected to sign the contract later that night or early Tuesday.

Rivers, taken by the New York Giants with the No. 4 pick in this year's draft, was acquired by Chargers in the deal that sent quarterback Eli Manning to New York. Manning was selected by San Diego with the No. 1 overall pick.

The 6-foot-5 Rivers, who missed four weeks of training camp and two preseason games, is unlikely to get the starting job immediately. In his absence, three-year veteran Drew Brees has performed well and will likely lead the team at the start of the season.

Rivers was a four-year starter at North Carolina State, where he set an NCAA record with 51 career starts and is the second-leading passer in NCAA history with 13,484 yards. He completed 72 percent of his passes last year, with 34 touchdowns. In four seasons, he threw 95 TD passes and completed 64 percent of his attempts.

While the Chargers got their quarterback, several other teams lost key players to injuries.

Seattle Seahawks' three-time Pro Bowl linebacker Chad Brown broke his left leg during practice Monday. And Baltimore lost center Mike Flynn, who started all but one game since becoming a starter in 2000.

Coach Mike Holmgren said Brown will undergo surgery as soon as possible and is expected to miss at least four regular-season games. He was hurt getting his feet tangled with tight end Itula Mili during a practice drill.

Flynn broke his right collarbone early in the Ravens' practice session. He was part of the unit that helped Jamal Lewis run for 2,066 yards last season, second highest total in NFL history.

New Orleans quarterback Aaron Brooks, who missed the first preseason game, will probably miss the third as well. He re-injured a ligament in the top of his thigh against the Packers. On Monday he was sore and back where he was when he first hurt himself.

Brooks said he doubted he would do much this week in practice or in the game.

"I think it's best for me to rest it and try to get the treatment I need so I can start getting ready for Seattle," Brooks said. "That's right around the corner."

Philadelphia signed 34-year-old Dorsey Levens to help fill the spot vacated at running back when Correll Buckhalter was lost for the season with a knee injury Friday against the Baltimore Ravens. Levens played for the Eagles two years ago and was with the New York Giants last year.Levens was signed by the Eagles the first time after Buckhalter was hurt and ran for 475 yards and a 5.5 yard-per-carry average."I don't have a lot of mileage on my body so I'm fresh," he said.Also, defensive end Jevon Kearse aggravated his sprained right ankle in Friday's game and did not practice Monday. The injury is not thought to be serious.

Linebacker Carlos Emmons returned to practice after spending more than two weeks on the sideline because of pain in the leg he broke last season."It's definitely a relief," Emmons said. "I have to work on things."The Giants signed the former Philadelphia Eagles player as a free agent in the offseason, thinking he would fill the spot that opened when Brandon Short left to sign with Carolina.Emmons practiced for the first week of training camp at the University at Albany. However, he developed pain in the leg around Aug. 6, the day before a practice session with the New York Jets.
