Former NBA player Desmond Mason is behind bars in Oklahoma after being arrested for a felony warrant out of Texas last week.

According to the local police department, Mason was picked up in Bricktown on Thursday … but was taken to a local hospital for treatment due to a medical issue before being booked.

Mason is still in the Oklahoma County Detention Center as of Monday … and is being held on “flight to avoid,” which is used for someone crossing borders to dodge prosecution, News 9 reports.

The outlet also stated the felony warrant is for theft of property out of Collin County. A couple claims they paid Mason — an artist in retirement — more than $9,000 to frame some sports memorabilia for them in March 2025 … but he never returned the item.

The couple said Mason was either MIA or had excuses for not delivering the finished product … and went to authorities to resolve the issue earlier this year.

The memorabilia as a whole is valued at $40,000, according to officials.

Mason is listed at 6’6″ and 270 pounds on his booking sheet.

Mason was a first-round pick to the Seattle SuperSonics in 2000 … and won the Dunk Contest in 2001. He also played for the Bucks, Hornets Thunder, and Kings before playing his final NBA game in 2009.
