Beal said his hamstring did not worsen after he scored 25 points and grabbed six rebounds in 35 minutes during the Wizards' 115-110 win over Charlotte on Sunday, clinching the eighth spot for Washington.
"There's no setbacks which is good," Beal said. "I didn't injure it any worse than what it was. Obviously it still probably won't be 100 percent. It is just a matter of managing it as best I can."
Washington head coach Scott Brooks said Beal "felt great" and that point guard Raul Neto, who missed Sunday's game with a strained left hamstring, will be a game-time decision against Boston on Tuesday night. Neto was later upgraded to probable.
Beal -- who shot 8-for-27 but said he learned what he could and couldn't do on his hamstring after the first half against Charlotte -- will continue to receive treatment on his hamstring before the Wizards play the seventh-seeded Celtics. Beal missed three straight games after straining the hamstring and not playing at the end of regulation and in overtime during a 133-132 overtime win over Indiana on May 8.
He called his decision to return and play against Charlotte a "hard-headed" one because he wasn't fully healthy but did not want to let his teammates down.
"I felt good," Beal said of how he was feeling after the game. "I would say I am not as sore as I thought I would be. Not as beat up as I would have thought."
