The Boston Celtics might have to do without important guard Avery Bradley for the remainder of the playoffs after the 25-year-old suffered a hamstring injury in the 101-102 loss to the Atlanta Hawks.
In a very close run affair, the Celtics fell on the road during Game One of their first-round playoff series, but the injury to Bradley may have a more profound effect on their fortunes.
Avery is an essential part of the strong defensive unit that comprises the Celtics this year. Although Isaiah Thomas usually steals the headlines - like he did with 27 points in the loss to the Hawks - Bradley complements the explosive point guard extremely well at the two spot.
Coach Brad Stevens knows how important the Washington-born star is to his starting five and offered a less than encouraging diagnosis via his resident shooting guard.
''He's very, very sore,'' Stevens said. ''He said on the court that he heard a pop.''
A pop suggests we might have seen the last of Bradley in this playoff series and therefore, probably, this season.
If he has torn his hamstring, he will surely be ok to return next season after a few months of rehabilitation.
The Celtics will hope so; Boston are on the cusp of developing a really strong side if they can make some smart moves in the summer.
