The Boston Celtics have been the surprise of this season. After trading away Isaiah Thomas, Jae Crowder, and Avery Bradley last year, many believed that the Celtics' run atop the Eastern Conference would cease. That turned out to be quite the contrary. The Celtics are currently the second-best team in the Eastern Conference. They have been rejuvenated as title contenders and could be a thorn in the side of some person named LeBron James in the postseason.

Though, at this stretch of the season, the Celtics have faced some adversity that could affect their rankings. Recently, the Celtics lost Kyrie Irving to some nagging knee injuries, and have lost Jaylen Brown as well after a nasty fall on his head. To make matters worse, the Celtics have to deal with Marcus Smart's pesky thumb injury. There have been some conflicting reports about Smart's thumb injury, but Danny Ainge appears to know what's going on, per the Boston Herald's Mark Murphy.

Danny Ainge said Monday night the team won’t know for “a couple of days” about the extent of Smart’s injury. He added the team doesn’t know whether surgery will be required, and it’s unclear whether Smart will be able to play again this season. Ainge disputed a report that Smart had suffered a torn tendon, saying instead that Smart had suffered ligament damage near the thumb.

Smart lacerated his thumb earlier this year after smashing his hand against some glass at a hotel. Since then, his thumb hasn't really improved and he may need some more time to heal before he can make a big impact for the Celtics this year.
