Four to compete for All-Star dunk title

Indiana's Paul George, Minnesota's Derrick Star weekend.

The Slam Dunk contest will take place on February 25 at Amway Center in Orlando, one day before the All-Star Game.

Last year's champion, Blake Griffin of the Los Angeles Clippers, decided against participating.

A new format will be implemented for this year's competition. The contest will consist of only one round and each competitor will execute three dunks.

Fan voting will open after all four players have completed their first dunk. Previously, the dunk contest consisted of two rounds, with the first round scored by a panel of judges which determined two finalists.

Beginning this year, only fan voting will be utilized in determining the winner and voting also will expand to social media. For the first time ever, fans will be able to cast votes on Twitter by posting a corresponding letter assigned to each dunker. Since 2008, fans have determined the winner through texting and voting on NBA.com.
