The Brooklyn Nets' disappointing start to the season hit a low point with the loss of All-Star center Brook Lopez for the season to a broken foot, league sources confirmed Saturday. Lopez broke his surgically-repaired right foot that he fractured in 2011 and later had a screw replaced in. League sources say Lopez fractured the fifth metatarsal of his right foot. The injury was earlier reported by Comcast SportsNet New England. The 7-foot center was thought to have suffered the break sometime in the second half, possibly in the third quarter, during the Nets' overtime loss to the Philadelphia 76ers, a league source said. Lopez gutted his way through the injury, playing 44 minutes while making 9-of-19 shots and finishing with 22 points and seven rebounds. The Nets discovered the bad news after the game when Lopez underwent X-rays on his troublesome foot.
