The Memphis Grizzlies will debut three different O.J. Mayo billboards in Phoenix for All-Star Weekend as part of his Rookie of the Year campaign, which will kick off this weekend. The billboards feature Mayo and the tag line “Welcome to the Show.”

Be sure to watch Mayo play in the T-Mobile Rookie Challenge Friday night and the H-O-R-S-E competition on All-Star Saturday Night.

O.J. Mayo will take on Kevin Durant and Joe Johnson in the first ever H-O-R-S-E competition during All-Star Saturday night.

The contest will take place outdoors at the NBA’s All-Star Block Party on Saturday in Phoenix before TNT televises the All-Star Saturday night festivities.

If a player makes a shot in H-O-R-S-E, the next competitor must make the same shot or receive a letter. A player gets an ‘H’ for his first miss and is eliminated once he has all five letters of the word.

Players will have 24 seconds to execute their shots, and an NBA referee will rule if they’re done properly. Dunking won’t be allowed.
