After the Los Angeles Lakers lost to the defending champion Milwaukee Bucks 109-102 to fall to 8-8 this season, LeBron James opened the door to making his return from an abdominal strain on Friday in Boston. “I hope,” James told ESPN on Wednesday when asked if he would play against the Celtics after missing the past eight games and 10 of L.A.’s 16 games because of injury. “I hope.” While Lakers coach Frank Vogel said James is “day to day,” sources close to James told ESPN that there is a “50-50” chance he will be back in the lineup at the TD Garden.
