Metta World Peace was suspended seven games by the NBA Tuesday for his elbow to the head of Thunder guard James Harden in Sunday's game. The Lakers will be without their defensive specialist for the final regular-season game and the first six games of the postseason. This means he would at most miss two games of a potential second-round series between the teams.

Although World Peace insisted the elbow was accidental, even his own teammates didn't appear to be convinced.

The Saints' nightmarish offseason got a little worse Monday as the team denied an ESPN report that claimed general manager Mickey Loomis' booth in the Superdome was wired so he could listen to opposing coaches' radio communications during games.

The "Outside the Lines" report said the system was in place from 2002 until it was disabled following damage to the stadium from Hurricane Katrina in 2005. There was no determination if it was ever used.

Lakers guard Metta World Peace claims it was an accident, but even he acknowledges that the video makes him look bad delivering a vicious elbow to the head of Thunder guard James Harden during Sunday's game in Los Angeles.

World Peace was celebrating a dunk when he brushed up against Harden and then knocked him to the floor. World Peace was ejected from the game. Harden, who was on the floor for about a minute, also did not return to action. The Lakers went on to rally from an 18-point second-half deficit and win in double overtime, 114-106.

Dwight Howard will have back surgery and miss the remainder of the Magic's season as well as this summer's Olympics. Howard, who has missed his team's last six games, is scheduled to have the procedure to repair a herniated disk Friday in Los Angeles.

"It hurts [emotionally]," Howard told ESPN. "That's the first thing -- it hurts. And then with people saying and thinking I'm quitting on my team. This is a real issue. I tried to play through it and it just made my back worse."

According to a report from Yahoo! Sports' Adrian Wojnarowski, Bobcats coach Paul Silas shoved forward Tyrus Thomas after a postgame screaming match Sunday night, sparked by Thomas' friendly chatter with Celtics players.

Silas, the 68-year-old former Celtic, reportedly chastised Thomas for his fraternization with the C's, and Thomas yelled back at Silas. When Thomas stood up, Silas pushed him toward his locker before players stepped in to break up the altercation.

Marlins manager Ozzie Guillen returned Tuesday from a five-game team suspension for his comments praising Cuban dictator Fidel Castro, and he remained apologetic.

"I put myself on probation … me, nobody else," Guillen said. "It's probation about growing up and being better, and be careful to not trust too many people. That was my problem."

There were no demonstrations against Guillen prior to the Marlins' 5-2 victory over the Cubs, which drew a season-low 24,544 to Marlins Park in Miami.

Giants quarterback Eli Manning will host "Saturday Night Live" on May 5 after turning down the offer a few times before. He follows in the footsteps of his brother, Peyton, who hosted the show five years ago.

“I’m looking forward to it,” Eli said Monday, as the Giants gathered for their first offseason workout program. “It’s something that’s been offered a few times and I’ve turned it down. But it seemed like the right time. I felt ready to do it and I’m excited about that opportunity.”

Wesley Korir continued the Kenyan dominance at the Boston Marathon Monday, overcoming temperatures in the high 70s to rally for a victory over Levy Matebo in the 116th running of the Patriots' Day race. Korir, a 29-year-old who left his homeland to attend college in Kentucky at Murray State and then Louisville, finished in a time of 2 hours, 12 minutes, 40 seconds. A Kenyan has won Boston 19 out of the last 22 years, including three straight.

Former Celtics center Dwayne Schintzius died Sunday in Tampa from respiratory failure at the age of 43. According to his father, Schintzius had been being treated for complications from a failed bone marrow transplant after being diagnosed with leukemia in 2009.

The NHL acknowledged Thursday that a linesman missed an offsides call that led to the Flyers' first goal in Wednesday's playoff game vs. the Penguins.
