Cetlics: Smart out 4-6 weeks partially torn oblique muscle

Boston Celtics' Marcus Smart in action during an NBA basketball game against the Philadelphia 76ers Wednesday

Celtics guard Marcus Smart could miss the first two rounds of the National Basketball Association playoffs due to a torn oblique injury, according to ESPN's Adrian Wojnarowski.

Smart has been one of the Boston Celtics' most productive players. The forward limped off after playing just six minutes and it was revealed later the injury was sustained prior to the game against Magic.

In Smart's absence, the Celtics will nearly certainly revert back to Jaylen Brown as the team's starting shooting guard - as he was for the opening few weeks of Boston's season. Although they enter with home-court advantage in the first round of the playoffs, head coach Brad Stevens will have to shuffle his lineup once again after finally finding continuity with the five-man lineup of Smart, Aron Baynes, Al Horford, Jayson Tatum and Kyrie Irving. (Yeah, same.) The injury occurred at 6:44 in the third quarter of Sunday's game against Orlando, following contact with the Magic's Nikola Vucevic.

Will he be ready for the postseason, which is approaching this weekend?

"I really hope Marcus finally gets recognized as an All-Defensive team member", Stevens said in March. I try to play every game of the season but it was really bothering me. He tried to stay in the game but on the very next possession, collapsed in pain and had to be taken off the floor.

Ranked fourth in the Eastern Conference, the Celtics, who tote a 49-33 record, will face the resilient 48-34 Indiana Pacers in the opening round of the playoffs.
