The Dallas Mavericks will fill their freshly-vacated 15th roster spot by calling up Iowa Energy point guard Chris Wright from the D-League, according to sources familiar with the decision.

Sources said Wright will receive a 10-day contract before Tuesday's game at Milwaukee to fill the opening created by Saturday's release of 2011 championship alumnus Dominique Jones.

Wright was a McDonald's All-American in high school and then starred at Georgetown before going unselected in the 2011 NBA draft. He went to training camp with the New Orleans Hornets in October and then joined the Energy after failing to stick.

The 6-foot-1, 210 pounder averaged 15.5 points, 7.0 assists and 4.3 rebounds in 37.0 minutes per game for Iowa, earning a spot in last month's D-League All-Star game in Houston.

In March 2012, Wright was diagnosed with multiple sclerosis, but he has continued to play in the wake of the M.S. findings and was widely considered overdue for an NBA callup based on his development at the point.
