BOSTON (AP) -- Boston Celtics center Kevin Garnett says this weekend "is definitely my last All-Star game."

Garnett would not elaborate on why he wouldn't be back after playing in the midseason exhibition for the 15th time in his 18-year career. Garnett says he's bringing along friends and family so he can enjoy this weekend's game in Houston.

Is it possible that the 37-year-old Garnett is planning to retire?

He wouldn't say.

Garnett is averaging 15 points and 7.7 rebounds per game. He's helped the Celtics stay competitive - and even move up in the standings - despite the loss of fellow All-Star Rajon Rondo.
