And it's not a good thing.
LeBron James had to sit for most of the second quarter of tonight's Eastern Conference Finals game against the Celtics.
Midway through the quarter, James got an offensive foul on a drive to the hoop against Boston guard Terry Rozier. James has gotten plenty of offensive fouls before, but this one was historic.
It was his fourth foul of the first half. In James' 14-year career as an NBA player, he's never compiled four fouls in a first half. He's only had three playoff games with four total fouls over the last two seasons.
Here's video of the foul. He was pretty stunned by the call.
James' absence wasn't a killer for Cleveland, but it obviously didn't help.
Boston took a 10-point lead into halftime, going up 57-47, as the Celtics attempt to even the series at 2-2 heading into a critical Game 5 at home.
