Miami Dolphins wide receiver Greg Camarillo will miss the rest of the season with a knee injury, coach Tony Sparano said Monday.

Camarillo left Miami’s 48-28 loss to New England in the second half Sunday and did not return. He underwent an MRI on Monday.

“You don’t want to lose a player like that,” Sparano said. “He’s been really productive for us. To me, the guy’s been exactly what you’re looking for on your football team. I’m disappointed for him. I know how important it is for him.”

The tear in Camarillo’s knee ends his breakout year with the Dolphins. He leads the Dolphins with 55 receptions for 613 yards and two touchdowns after catching a total of eight passes in his first two NFL seasons.

“He’s a very, very consistent player,” said Casey Cramer, who has roomed with Camarillo for the past three games. “I just hope that he heals quickly and he gets back out as soon as he can. He’s a great guy.”

Camarillo did not think the injury was season-ending after Sunday’s game, his agent J.R. Rickert said.

“He’s in good spirits considering the circumstances,” Rickert said. “Greg is the kind of guy who really likes going out there every week and laying it on the line with his teammates.”

This is the second time in two years that the Dolphins have lost a key player during a game against the Patriots. Running back Ronnie Brown needed surgery to repair a torn ACL after the Dolphins’ 49-28 loss to New England on Oct. 21, 2007.

Camarillo signed a $6 million, three-year extension this year that will keep him under contract through 2011.

“It hurts to lose Greg, but I think we’ll be fine,” running back Patrick Cobbs said. “I think this team can pick it up and we can definitely move forward.”

New Orleans running back Reggie Bush is scheduled to undergo arthroscopic knee surgery Monday that is expected to sideline him three to four weeks, a Saints source told NFL Network’s Adam Schefter.

The Saints believe Bush has injured the meniscus in his left knee in Sunday’s loss to Carolina.

However, the Saints have a bye after their game in London against the Chargers, so Bush could wind up missing only one game, reports Schefter. But exactly how long Bush will be out, and how many games he will miss, will not be known until doctors perform Monday’s surgery.

Bush will not travel with the Saints to London.

Bush injured his left knee on a punt return late in the first half. He reversed field on his run, which ended when he stepped out of bounds on the Carolina sideline. He seemed to pull up a bit and favor his left leg after that.

Bush missed practice earlier this week with swelling in his left knee, but the Saints said the injury was not serious.

Bush had 55 yards on nine carries, caught one pass for 5 yards, and had a 3.5 average on three punt returns against Carolina.

Payton said the Saints became “one-dimensional” after Bush left the game, which the Panthers won 30-7.

But quarterback Drew Brees noted the Saints played the final four games of last season without Bush — they went 2-2 while he was out with a knee injury — and proved this year they could persevere when tight end Jeremy Shockey and receiver Marques Colston missed games.

“Of course it’s tough. He’s a big-time playmaker,” Brees said. “We’re going to miss him, and I hope he’s not out very long.”

Kim Kardashian and her NFL boyfriend Reggie Bush are in no hurry to tie the knot, despite rumours of an engagement.

Rumours started after “Kim Engaged! Never put a ring in someone’s dessert. They could SWALLOW IT!!!!” was posted on her Facebook page at 4:35 am on October 14.

A representative for Kardashian has denied the engagement being true, calling it just a rumour. “It’s a rumor,” Usmagazine.com quoted Kardashian’s rep as saying. “She doesn’t even have a Facebook page!” the rep added.

The two, who have been dating since April 2007, have admitted that marriage is definitely on the cards. “That’s definitely where we are heading,” Kardashian revealed.

“That’s something that we do talk about,” she said.

“I think that when you spend so much time with someone who is such a big part of your life, that’s definitely the future,” she added.

Miami Dolphins linebacker Joey Porter was fined $20,000 Friday by the NFL for comments critical of beleaguered referee Ed Hochuli and his crew in Sunday’s loss at Houston.On the first play of the Texans’ drive for the winning touchdown late in the game, Porter stripped quarterback Matt Schaub. Hochuli ruled the play an incomplete pass rather than a fumble, saying Schaub’s arm was moving forward when hit.

“I know for sure that I had both his arms when the ball came out,” Porter said after the game. “I’m looking for an apology or something on Tuesday or Wednesday on NFL Network, but it will be too late by then. The game’s over. …

“I thought we won the game, actually, but they kept getting calls.”

Hochuli has been at the center of several disputed decisions this season, included a call he acknowledged he blew that helped Denver rally past San Diego.

Free agent running back Shaun Alexander’s workout with the Washington Redskins went well, and the team offered him a one-year, veteran minimum contract, the Washington Post reports.

Adam Schefter of the NFL Network reports that the 31-year-old Alexander and punter Ryan Plackemeier both signed contracts with the Redskins on Tuesday. Both had tryouts with the team earlier Tuesday, and both players previously worked with Redskins coach Jim Zorn in Seattle.

The team needed a running back after Ladell Betts suffered a sprained left knee that will keep him out for at least two weeks.

The Redskins decided to make a change at punter after Brooks had an uneven performance against the Rams, sticking a 50-yard punt at the Rams’ 3-yard line but later kicking a 26-yarder that drew boos from the crowd
