Player didn't call the last bet but tabled his boat

[jesse8888]

Live 6/12 game. Lots of betting, and on the river player 1 bets out and player 2 raises. The action is headsup. Player 2 said very clearly (at least I heard it) "raizit" in his russian accent. Player 1 tables his hand without calling the bet. Player 2 says "send it" and opens his straight. Player 1 has a boat. The dealer reads both hands, and pushes the pot to player 1, after destroying the board and both hands (putting them back in the much/stub pile).

Floor is called over and the ruling is upheld. Is this correct?
