Boston's Game 5 win over Milwaukee didn't come without a little controversy.

The Celtics beat the Bucks 92-87 on Tuesday to take a 3-2 series lead, and a missed shot-clock violation in the final two minutes of the fourth quarter gave Boston just the momentum it needed to seal the victory.

After escaping a backcourt violation, the Celtics burned the clock until Al Horford launched a jumper after time on the shot clock had already expired.

"It's bull—," Bucks point guard Eric Bledsoe said after the game, via Sporting News' Sean Deveney.

Referee crew chief Ken Mauer responded to the call — or lack thereof — and offered an explanation when the game finished.

"The rule states that under two minutes we are not allowed to review a potential 24-second violation unless the ball goes in the basket," Mauer told a pool reporter, via ESPN.

The Bucks will look to even the series and avoid elimination when they host the Celtics at 8 p.m. ET Thursday.
