Pocket Jacks... lost half my stack.

In a home tourney Saturday the following happened to me. Dealt pocket Jacks UTG, I call call the BB. There was no preflop raise with 3 players in the hand. The flop is 9 [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/diamond.gif[/img] . I come out with a $400 bet. Player to my left calls as does BB. Turn is a 10 [img]/images/graemlins/diamond.gif[/img], I check, hoping for someone bet with A9 or A10... Checks around the table. River is a 7 [img]/images/graemlins/heart.gif[/img]. I bet again 400, and again I get called from both players. I show my pocket jacks, player to my left shows A9 as I predicted, what does the BB roll over to beat me?
