Yankees third baseman Alex Rodriguez recently traveled to Germany for experimental therapy on his right knee, according to a New York Post report. Rodriguez received a recommendation from Lakers star Kobe Bryant before getting Orthokine, which involves taking blood from a patient's arm and spinning it in a centrifuge before injecting it into the injured area.

Jets coach Rex Ryan said Monday that he doesn't plan to change his brash behavior, even after his boasting backfired with Saturday's loss to the fired-up Giants.

The NFL will not investigate the on-field incident after Saturday's game between the Jets and Giants, in which Rex Ryan exchanged some words with Giants running back Brandon Jacobs.

Ryan, who was fined $75,000 for swearing at a fan who mocked him at halftime of the Jets' loss to the Patriots earlier this season, met Jacobs at midfield after the Giants' 29-14 victory.

The latest Tim Tebow controversy centers around a cardboard cutout of the Broncos quarterback that an individual inserted in a nativity scene in a Florida park. A county staffer, responding to a handful of complaints, last week removed the image of the former University of Florida star that had been placed next to the baby Jesus.

However, on Monday Tebow was returned to his spot alongside the Three Wise Men, with Polk County communications director Mianne Nelson saying its presence apparently did not violate county policy.

The Jets and Giants play Saturday, and despite coach Tom Coughlin's request that his team not get caught up in a verbal back-and-forth with Rex Ryan and friends, the Giants can't help themselves.

Ryan has been trying to claim that the Jets are taking over New York from the Giants.

Said Giants running back Brandon Jacobs: "They're going to need a hell of a lot more than this game to make that happen."

10. The Miami Heat

Popular Canadian singer Michael Buble, a lifelong Canucks fan, skated with the team Tuesday at practice. The 36-year-old hit the post on a shootout attempt against Roberto Luongo and called the experience "just the greatest day of my life, really."

Buble, a multiple Grammy Award-winner who was the musical guest on "Saturday Night Live" over the weekend, said he doesn't understand how the Canucks can be reviled around the league.

Longtime Philadelphia Daily News sports writer Bill Conlin, who was inducted into the Baseball Hall of Fame this year, was accused by relatives and former neighbors of sexually molesting children in the 1970s.

Soft-spoken children's singer Raffi Cavoukian is taking on loud-mouthed hockey analyst Don Cherry. Raffi, a Canadian who is best known for songs such as "Baby Beluga" and "Down by the Bay," started a Twitter campaign in which he encourages fans to mute Cherry following the former Bruins coach's rant against people who want to eliminate fighting from the sport.

Panthers tight end Jeremy Shockey wasn't happy with his team's loss to the Texans Sunday. Shockey also was upset about what he considered a lack of decorum by Houston players during the national anthem.

"I was pretty upset in the way that they weren't showing respect to America during the national anthem," Shockey said. "There were about 10 players that didn't put their arms across their chest. This is America. You should at least respect America."
