The Dallas Mavericks did not offer a second 10-day contract to point guard Chris Wright, the only player in NBA history known to have multiple sclerosis.
The decision was made Friday night after the Mavericks defeated the Boston Celtics.
Wright appeared in three games for a total of four minutes since signing with Dallas last week. The NBA D-League all-star is averaging 15.5 points and seven assists per game for the Iowa Energy.
Wright was diagnosed with MS last year while playing professionally in Turkey. He was told his playing days were over but he competed in training camp with the New Orleans Hornets in the preseason before playing for Iowa.
The 23-year-old out of Georgetown scored one basket on March 15 against the Cleveland Cavaliers and got to keep the game ball.
"He's been an inspirational figure to a lot of people," coach Rick Carlisle told ESPN Dallas. "He's an NBA-caliber player. There's no doubt about that. You do what he's doing -- playing a professional sport with MS -- that's going to be something that a lot of people pay attention to. It shows his motivation, his determination, but it also shows the progress that's been made in that area.
"It's going to give people hope. That's a great thing."
