What the hell did Hellmuth have?

Sorel Mizzi Doubles Up Against Hellmuth
On a board of A94 Sorel Mizzi bets $80,000 and Phil Hellmuth calls. The turn is the A and Mizzi bets $180,000. Hellmuth goes into the tank then says, "I need a jack!" then calls. The river is the J, Mizzi thinks then finally goes all in for his last $323,000. Hellmuth quickly calls but mucks as soon as he sees Mizzi's 99. Mizzi now has $1.5 million and Hellmuth has around 1 million.

Maybe this is obvious to you guys, but what could that J have possibly done for his hand? AJ wins, JJ wins, no straight? [img]/images/graemlins/confused.gif[/img]
