Tyrese Maxey's thoughts were elsewhere after scoring 50 points in the Sixers win Sunday ... he dedicated the career-best performance to teammate Kelly Oubre Jr. after the star guard was badly hurt in a hit-and-run accident the day before.
As we previously reported, Oubre Jr. -- who joined the 76ers in September -- suffered broken ribs and other injuries when he was hit by a vehicle while walking in Philly on Saturday, hospitalizing the NBA star.
The Sixers played the Pacers the day after the accident ... and Maxey went off, dropping 50 points, with 7 rebounds, 5 assists, and 3 blocks!
