Call this river raise?

[MrStretchie]

Don't have the HH, but basically the deal is

Hero is in LP with TJ. Weak player in EP, solid player in MP. 1 bet apiece preflop.

Flop is TJ6r.

Check, check, Bet..

Turn: 3 of bricks
Check, check, Bet..

River: 7

Check, check, Bet, WP calls, SP Raises..

He has 89. If he doesn't have 89, he has a slowplayed set. Hero folds, right?
