Alameda, Calif. ? Jerry Rice has signed a six-year, $30 million contract extension that will give the Oakland Raiders more salary cap room.

Tim Brown, the longest-tenured Raider with all 15 of his seasons in Oakland, also signed an extension — which means the NFL’s oldest receiving tandem will stay together for now.

If the 40-year-old Rice were to play out the contract, which is unlikely, he would play until he’s 46. Last year, he suggested that he might play until he was 45.

“Coupled with Jerry Porter, they were as productive as any receiver trio in recent memory,” Raiders senior assistant Bruce Allen said Tuesday. “We’re happy to have them back, and I’m sure Rich Gannon is as well.”

The AFC champions were more than $30 million over the salary cap, with some estimates as high as $50 million.

Rice received a signing bonus, and the deal is “back-end loaded,” his agent, Jim Steiner, said, meaning much of his salary would be paid out in those final years.

“We’re happy with the deal,” said Steiner, who has reworked Rice’s contract almost every season. “Jerry’s happy with the deal. They appreciate Jerry’s contributions. Since he left the 49ers, it has worked out perfectly well.”

Steiner even suggested that Rice could stick around for the whole deal.

“It could happen,” Steiner said. “He takes it year to year based on how he feels and how he’s playing. Who knows.”

Rice had 92 catches for 1,211 yards and seven touchdowns in his 18th NFL season, a testament to his disciplined preparation and conditioning regimen. He joined the Raiders after the 2000 season.

Rice signed a six-year, 0-million contract extension Tuesday to remain with the Raiders, a salary-cap-motivated deal that theoretically could keep the star receiver playing until he's 46. Brown, the longest-tenured Raider with all 15 of his NFL seasons being in Oakland, also signed an extension Tuesday to keep the league's oldest receiving tandem intact.
