While it is unclear how many games Smart will miss with this latest injury, it is a tough blow for the Celtics.
Shortly after this, Shams Charania of The Vertical reported the tendon was torn, and that Smart will be seeking a second opinion.
You know things are not going well on the injury front in Boston when the "good" news is Kyrie Irving is only going to miss a few games with knee soreness. Daniel Theis is out for the rest of the season after tearing his meniscus.
The Boston Celtics will not have guard Marcus Smart in the lineup for quite some time after he reportedly tore a tendon in his thumb. Smart is averaging 10.2 points per game for the Celtics, and he is their best on-ball perimeter defender. Smart scored 20 points with eight assists, seven rebounds and four steals against the Pacers on Sunday (Monday, PHL time).
Boston, having already clinched a playoff berth, can use the remainder of the regular season to get healthy. After having the best record in the Eastern Conference for most of the young season, they are now 3.5 games behind the Toronto Raptors as they look to make one final push for homecourt advantage.
