WALTHAM — You’ve heard of getting your juices going to get into a game. Well, Shaquille O’Neal  put a whole new twist on that approach Tuesday when asked to describe how’s he feeling after missing the last two games.
O’Neal said before Tuesday’s practice that his sore right calf is “getting better” and is optimistic that he will be ready for Wednesday night’s game at Madison Square Garden against Amare Stoudemire and the New York Knicks . He worked out on the side and in the weight room but did not practice with the team.
“I’m doing better,” O’Neal said. “My calf juices are getting back up there. I’ll be alright.”
Doc Rivers  said that he would see how O’Neal comes through Tuesday’s practice before making a determination on whether to play him Wednesday night against a revitalized Knicks team that has won eight straight and stands just four games behind the 19-4 Celtics  in the Atlantic Division.
Semih Erden has filled in for O’Neal the last two games in the starting lineup.
