National Basketball Players Association Executive Director Michele Roberts has started setting up the union’s senior management with her first appointments, a group that includes a former president of the NFL Players Association.

Roberts announced the appointments Wednesday.

Dominique Foxworth, a seven-year NFL veteran who finished his term as president of the NFL players’ union last March, will start as the chief operating officer in January after finishing his master’s degree at Harvard Business School.

Attorney Gary Kohlman will be general counsel. Roger Mason Jr., a 10-year NBA veteran and longtime member of the union’s executive committee, will be director of player relations. Another former NBA player, Walter Palmer, will be director of international relations and marketing. Ron Klempner, deputy general counsel and acting executive director, now is senior counsel for collective bargaining.

ROOKIE OUT FOR YEAR — Los Angeles Lakers rookie forward Julius Randle, 19, is expected to miss the rest of the season after undergoing surgery on his broken right leg.

The seventh overall pick out of Kentucky broke his leg in the fourth quarter of his NBA debut in Los Angeles’ season-opening loss to the Houston Rockets on Tuesday. Before Wednesday’s game at Phoenix, the Lakers announced that Randle’s injury was just as serious as it appeared.

KINGS BREAK GROUND — The Sacramento Kings have officially broken ground on their new downtown arena.

Sacramento Mayor Kevin Johnson, Kings owner Vivek Ranadive and other city and team leaders gathered for a ceremonial groundbreaking at Downtown Plaza, though work at the site started months ago. The $477 million arena is expected to open for the 2016-17 season.

TAYLOR PLEADS GUILTY — Charlotte Hornets forward Jeffery Taylor pleaded guilty to a domestic violence charge and admitted he pushed his girlfriend at a hotel in Michigan.

Taylor pleaded guilty in East Lansing District Court to domestic abuse and malicious destruction of property charges. He faces up to 93 days in jail, but prosecutors say they won’t oppose a diversion program that could clear Taylor’s record if he complies with probation rules.

In exchange for the plea, prosecutors dropped an assault and battery charge involving an employee at a Marriot hotel in East Lansing. Authorities have said that Taylor attacked his girlfriend and the employee Sept. 25.
