The injury floodgates have opened.

Via CSNNE:

Paul Pierce will miss the Celtics’ upcoming four-game road trip, and may be sidelined for as many as two weeks, because of a knee problem that required a medical procedure on Wednesday.

Team owner Wyc Grousbeck said Pierce began feeling discomfort in the knee after Tuesday night’s victory over Indiana. He described the problem as an infection that required drainage, but said he wouldn’t describe the procedure as surgery.

Uh-oh.  More to come later.
