"I'm really excited about this opportunity," Johnson said. "I've always wanted to play in this game."
Johnson, who will drive to Lake Buena Vista from Delray Beach tonight, said he is looking forward to the competition.
"I'm pretty much just excited about competing against the best players in the nation," Johnson said.
With the addition of Johnson, Florida has eight players who were invited to participate in the Under Armour All-America Game. Safety commit Marcell Harris and linebacker commit Matt Rolin are not playing in the game because of previous injuries.
