David Dao, the doctor who was dragged off the United flight, made a killing on the World Series of Poker while his medical license was suspended in Kentucky.
Dao joined the poker circuit in July 2006 -- one year after his medical license was suspended due to multiple convictions for illegally prescribing painkillers.
In 2009, he came in 2nd in a tournament and walked away with more than $117k.
His player profile shows total earnings of $234,664 in the WSOP.
Some of Dao's competitors are starting to realize he's the same guy from the United incident.
