Guard Markelle Fultz joined the Philadelphia 76ers to continue therapy in a shoulder condition, pressing for a return to the lineup this season, league sources told ESPN.
There is still no timetable for Fultz to play again this year, league sources said.
Fultz flew in a red-eye flight from Los Angeles and arrived in Philadelphia on Saturday, where he met with Sixers officials before today's game against Oklahoma City, the sources said.
Fultz, the No. 1 pick in the 2017 NBA draft, left the Sixers to meet with medical specialists on November 21 and has not played a game since. He was diagnosed with a condition called thoracic outlet syndrome and has been working with therapists in Los Angeles since December 6, but returned east for a brief visit at Christmas.
Fultz's agent, Raymond Brothers, told ESPN three weeks ago that his client is progressing well in rehabilitating his right shoulder and expects Fultz to return to the team this season. "We want to make sure he's 100 percent healthy when he gets back," Brothers told ESPN at Christmas.
The brothers said Fultz has been regaining strength and mobility in his right shoulder, which the agent believes will improve the jump shot that has failed him so far in the league.
On the advice of the brothers, Fultz visited multiple specialists in late November and early December. The brothers told ESPN in early December that the thoracic outlet syndrome "affects the nerves between the neck and the shoulder, resulting in abnormal functional movement and range of motion, severely limiting Markelle's ability to launch a basketball".
There was a member of the Sixers medical team in each of the visits to the specialists.
Fultz has lost the ability to carry out and comply with long jump shots, and there has been an internal and external debate about how much of this baffling circumstance is physical rather than mental.
"People said it was a mental problem, and it's not," Brothers told ESPN in early December. "There's no way you're the first team in the world and suddenly you can not raise your arms constantly to shoot a basketball, something is physically wrong, now we have the answer to that problem."
