Andre Agassi just did it. Again.

Eight years after leaving Nike to sign with Adidas, Agassi reunited with the Swoosh on Monday.

The tennis Hall of Famer posted a photo on his Facebook page that shows him standing under the famed Nike logo. The caption was simple and direct:

Agassi, 43, was not immediately available for comment. But Nike confirmed that Hall of Famer was back in its fold through a press release that included this quote from Agassi:

"Nike has opened new horizons through its Designed to Move campaign, while consistently and historically championing health and fitness. Coming back together through this partnership will have a multiplying effect on this and future generations."

Nike, the American College of Sports Medicine and the International Council of Science & Physical Education are among the groups involved with Designed To Move, a project that promotes physical activity, particularly with children. This combination of helping kids and advocating fitness should be an attractive blend for Agassi.

Since retiring from tennis in 2006, Agassi has devoted much of his time to improving education across America. He founded a charter school in Las Vegas in 2001, and then in 2011, he launched a campaign to provide $500 million of funding for 75 charter schools nationwide.

Last year Agassi and his trainer, Gil Reyes, introduced a line of fitness equipment called BILT that's based on the customized pieces of gym equipment he used during his career. One of them, known as the Change Of Direction (COD) Machine, won an industry award for its design and safety.

"As a philanthropist and campaigner, he continues to share Nike's commitment to inspire the young generation with his Just Do It spirit," Nike co-founder and chairman Phil Knight said in a statement. "We are honored to welcome him back."

Back in 2005, the Los Angeles Times reported that one of the reasons Agassi left Nike was the "willingness of Adidas to also support Agassi's charitable foundation and other initiatives." Additionally, Agassi's wife, Steffi Graf, wore Adidas throughout her career.

It seems that everything Robert Griffin III touches turns to gold.

A year after winning the Heisman Trophy at Baylor, Griffin led the Washington Redskins on a remarkable turnaround that ended in a surprising playoff berth. So, just how valuable has Griffin become for the Redskins and their fans?

A pair of pink cleats worn and signed by Griffin were recently auctioned off for a whopping $15,000 at an American Cancer Society auction which raised money for the organization. The shoes beat out a Super Bowl package and a Redskins VIP experience as the most expensive item at the auction.

The new owner of the shoes, a Texas real estate investor named Gerald Haddock, will add them to a small shrine he has to Griffin in the corner of his office. Haddock, a Baylor alum, told the Washington Post that he also has a jersey, a helmet and a signed football.

"My family loves the Snyders," Haddock said of Washington owner Dan Snyder and his family. "We love doing something for the organization. It’s not about the shoes, but it is about honoring them and the organization. And Robert Griffin. Robert Griffin means as much to us in Texas and to the people who supported him at Baylor, as he does to the family of Washington. And so it’s really a combination of all those things."

Sara Kogod of the Washington Post wrote that Griffin also posed for 18 photos (which he later autographed) for $1,000 at the auction. So in essence he single-handedly raised more than $30,000 for the American Cancer Society.

Knicks Iman Shumpert guard made a statement with his incredible put-back dunk during the first half of New York's Game 2 victory over the Indiana Pacers.

Then, after the game Shumpert made a different sort of statement with his shoes.

The second-year guard, known for his (sometimes questionable) fashion, was spotted wearing bright, technicolor kicks.

The winged shoes look a little like a pair of patriotic shoes that Ryan Lochte donned a few months ago. Let's hope that Shumpert doesn't go with a custom-made grill later on in the playoffs, as Lochte did in the Olympics.

And for that matter, let's hope that Lochte doesn't try to emulate Shumpert's hair.

The Force will be with the Toledo Mud Hens next weekend.

The Triple-A affiliate of the Detroit Tigers recently revealed the jerseys that they'll be wearing for their series next weekend, and they truly look like they are from a universe far, far away.

As you'll see above, the Mud Hens' uniforms are Chewbacca-themed, perhaps a first in professional sports. At first glance they look pretty ugly, but are they so hideous as to be beautiful? Decide for yourself.

The themed jerseys, which will be auctioned off for local charities after the game, are just one part of the Mud Hens' Star Wars tribute.

According to the team's website, the Mud Hens are sponsoring a Kazoo giveaway (so fans can participate when music from the movie is played) and will have themed food (Yoda Soda, Darth Chocolate Brownie Sundae, etc.). There will also be Star Wars sound effects throughout the game and appearances by Star Wars characters.
