Paul Pierce worked up a light sweat before tonight’s game between the Celtics and Raptors and said he will return to practice tomorrow after missing the team’s final two exhibition game because of an infected middle left finger. Although the finger was puffy before the contest, Pierce said it had dramatically improved since he was sent home from New Jersey after shootaround Tuesday. He was even able to do some light shooting during the pregame warmup period.
‘‘It’s a lot better,’’ said Pierce. ‘‘I just had it drained [Tuesday] due to infection. That’s basically it. I’m going to take care of this infection. I’m taking antibiotics. The swelling went down. It was hurting for a few days, but nothing that really bothered me to where I [thought to] look into it. But going to shootaround [in New Jersey], it was real sore and it swelled up to the point where I couldn’t even catch the ball without pain. It was obvious swelling. I’m doing the necessary things to be ready.
‘‘I went out and shot on it and it’s doing good. Doctors are taking extra precautions until they find out about the infection a little bit more. I’m going to sit out tonight and just make sure I’m ready for the regular season.’’
