A hand from the $10,000 even at Foxwoods

[Shammu]

I have about 12,000 chips, blind are 100/200, I am BB with 99, a middle player raised to 800 so I called him, was that the right play? the flop comes 10s 9s 3h, I checked and he bet 1,000, what would your move be? he has about the same chip stack as I have, I was moved to the table shortly before and did not see him play any hand. Would you call or raise?
