In an attempt to strengthen his arthritic right knee, Lakers star Kobe Bryant reportedly went to Germany and had a procedure similar to platelet-rich plasma therapy.

Roger Clemens' attorneys filed a motion Wednesday night claiming that former trainer Brian McNamee sold out Clemens to protect himself from federal investigators after an incident in St. Petersburg, Fla., in 2001.

McNamee, who later admitted he lied to the investigators — claiming he was trying to protect Yankees players at the party — was never charged.

Without a doubt, “tradition” is one of the most grossly overused words in the English language. We use it to describe everything from the changing of the guards at the Tomb of the Unknowns to the mayor of Punxsutawny pulling a giant rat out of the ground every February 2nd.

Jets free agent safety Eric Smith is not supportive of the players' group workouts during the work stoppage. "I don’t understand why guys are doing this stuff," he told The Washington Post. "You’re risking injury. And you got the rookies who aren’t getting paid any money, flying in to do these workouts. So they’re putting themselves in a hole before they make any money."

Smith, 28, who will be a free agent, returned home to Ohio and has been living with his parents and working out on his own.

Rangers forward Sean Avery, who aggressively supported gay marriage in New York — a bill making gay marriage legal in the state was passed last week — now wants the league to get behind him.

Former Red Sox star Wade Boggs, whose most famous television acting gig was a guest spot as himself in an episode of "Cheers" in the 1980s, appeared in the Syfy channel's original movie "Swamp Shark," which debuted Saturday night.

Lakers guard Ron Artest, whose actions helped spark the most embarrassing brawl in NBA history in 2004, is changing his name to Metta World Peace. Metta is a Buddhist term meaning loving-kindness. Artest's attorney filed a petition in court, and it will be considered on Aug. 26.

Former Giants running back Tiki Barber, attempting an NFL comeback after a stint as a talking head on NBC, did an interview with New York sports radio host Mike Francesca Wednesday, and it did not go well. "The guys at NBC, and I know all of them, they felt that you did a bad job, and they said you thought you were entitled," Francesa said, telling Barber he was fired after his stint was a "failure."

According to several reports, legendary Boston crime boss James "Whitey" Bulger was arrested Wednesday in Santa Monica, Calif. The 81-year-old Bulger, who had been on the run from authorities since 1995 when federal agents were about to arrest him in connection with 21 killings, took place inside a Southern California building without an incident, according to reports. According to The Los Angeles Times, the FBI had been conducting a surveillance operation in the area where the arrest was made.

The NFL might be in a work stoppage, but the Eagles and Giants haven't toned down their feud. Days after Eagles receiver LeSean McCoy called Giants running back Osi Umenyiora "overrated" and "soft" (and was threatened by Umenyiora in return), Giants receiver Steve Smith posted photos on his yfrog account showing his team celebrating the Super Bowl XLII title around a picture of an empty Eagles trophy case.
