Knicks coach Mike D'Antoni said a knee injury suffered in practice Monday by star forward Carmelo Anthony was not serious.

Anthony hyperextended his left knee as he came off a screen and stepped on rookie Iman Shumpert's foot.

Anthony hit the floor and stayed down for 30 seconds as a hush fell over the practice.

When he got up, he appeared ready to continue but then he walked off the court after one possession to the trainer's room and did not return.

D'Antoni said he considered Anthony day-to-day and expects him to return to practice Tuesday or Wednesday.

The 27-year-old had surgery on his left knee in the offseason, saying in September that he had been bothered for years by pain in the knee. The four-time All-Star also underwent a procedure on his left elbow.
