Key Celtics player will miss time for injuring himself in the dumbest way imaginable

What on earth was he thinking?

Boston Celtics guard Marcus Smart will miss approximately two weeks after suffering lacerations to his right hand from a non-basketball incident, the team announced Friday afternoon.

Smart missed Wednesday night's game against the Los Angeles Clippers with an unknown injury, but Celtics head coach Brad Stevens told reporters prior to the game that he only knew that Smart received stitches and that he was still working to get the full story. He later said that he believed Smart cut his hand on some glass in his hotel room.

While the team offered very few details on the incident, Smart gave more information in a tweet:

It's unclear why Smart hit a picture frame on the wall, but this revelation has to be one of the more obscure reasons we've heard in recent memory for a player injury. While his injury was certainly preventable, the team did catch a break that his injury isn't serious and that he's only expected to miss a couple of weeks.

Smart has established himself as one of the most important players on the Celtics given his ability to impact games in a variety of different ways. In 46 games this season, Smart is averaging 10.1 points, 4.7 assists, 3.5 rebounds and 1.3 steals per game.
