Who gets the KITN?

[pvn]

Horseshoe Tunica, 1/3 NL.

Heads up on the turn. Player A bets out $65. Player B announces "raise" and says "265". Player A says "I call, that puts me all in." Player B has laid out the $65 to call, and two stacks of red chips. Player A only has the $65 out.

Dealer throws the river, both players flip up their cards. Player B's hand is good.

Now, it turns out that player A had $241 behind, so the $200 more did NOT put him all in. He ships two stacks of red into the middle, but hangs on to the $41. Player B wants the $41.

Floor is called.

What's your ruling?
