New York Knicks guard Stephon Marbury, who hasn't missed a game due to injury in five years, is doubtful for Wednesday's game at Chicago because of a sprained left shoulder.

Marbury was hurt in the fourth quarter of Monday's loss to Minnesota. X-rays after the game revealed no fracture, but Marbury's arm was in a sling Tuesday and he did not practice.

Marbury also could miss Thursday's home game against Detroit. He has played in 280 consecutive games, the league's fifth-longest current streak, and hasn't missed a game since Oct. 30, 2002, when he was suspended by the NBA for the Phoenix Suns' season opener.

"It means a lot but I'm just going to have to start up another one if I don't play tomorrow," Marbury said. "I play basketball for a living and this is what I do. I feel like for the money that we make that we're supposed to play through pain and through all of the things that we go through."
