Dec. 5 (UPI) -- Philadelphia 76ers guard Markelle Fultz could miss more than a month of time while rehabilitating his right shoulder.
The 76ers announced on Tuesday that Fultz was diagnosed with Thoracic Outlet Syndrome. Fultz completed a "thorough series of consultations with specialists across several disciplines," according to the 76ers.
"Thoracic Outlet Sydrome, which involves compression or irritation in the thoracic outlet (area between lower neck and upper chest), was identified," the team said in a statement.
"Physical therapy was recommended for Fultz before returning to play. Fultz will begin this physical therapy immediately, is out indefinitely, and further updates will be provided as appropriate."
Fultz, 20, is averaging 8.2 points, 3.7 rebounds and 3.1 assists in 19 games this season. The No. 1 overall pick in the 2017 NBA Draft posted 7.1 points, 3.1 rebounds and 3.8 assists in 14 games during his rookie campaign. Fultz hasn't played since posting one rebound, one assists and zero points in 7:05 on Nov. 19 against the Phoenix Suns.
Sources told The Athletic that Fultz will work with former Los Angeles Lakers physical therapist Judy Seto during his rehab. Fultz's agent Raymond Brothers told ESPN that the ailment is "severely limiting Markelle's ability to shoot a basketball."
The Sixers face the Toronto Raptors at 8 p.m. on Wednesday at Scotiabank Arena in Toronto.
