VJ Edgecombe is the latest significant addition to the Sixers’ list of sidelined players.  A Sixers official said Wednesday afternoon that an MRI on Edgecombe confirmed the rookie suffered a lumbar contusion during the team’s blowout loss Tuesday night to the Spurs.  Edgecombe will miss the Sixers’ matchup Wednesday vs. the Jazz. He’ll be re-evaluated before the Sixers visit the Hawks on Saturday.  The 20-year-old guard picked up his back injury when he thudded to the floor after being fouled by Carter Bryant on a three-point attempt with 0.2 seconds left in the second quarter. He was officially ruled out at halftime. Backcourt mate Tyrese Maxey went to the Sixers’ locker room to see Edgecombe in the third quarter.  “No one likes getting hurt, but he was the same — smiling, happy,” Maxey said. “We had a good conversation. That’s my little bro. I’m going to check on him; I couldn’t continue the game without checking on him.” Edgecombe’s played in 57 of the Sixers’ first 61 games and averaged 35.1 minutes. He’s posted 15.3 points, 5.5 rebounds, 3.9 assists and 1.5 steals per contest during an excellent rookie season.  The 33-28 Sixers will remain without Joel Embiid (strained right oblique), Kelly Oubre Jr. (illness), Paul George (suspension) and Johni Broome (right knee meniscus surgery recovery) against the 18-43 Jazz. Quentin Grimes started in Oubre’s usual spot on Tuesday and Cameron Payne opened the second half instead of Edgecombe. Utah enters Wednesday on a six-game losing streak and down several key players, including Lauri Markkanen, Jaren Jackson Jr. and Walker Kessler.  ...read more read less
