His status was unknown after he withdrew from last week's WGC Firestone due to a back injury. He missed four months of the 2014 season after having back surgery, and hasn't played well since returning.
It looks like he intends to play, but there's no official word. He has until his 8:35 a.m. tee time on Thursday morning to register for the tournament after being granted an extension.
Golf reporters have been staking out his parking spot for days. He still isn't parked there, but according to the PGA he's at Valhalla:
