Kevin Porter’s injury serious?

Cleveland Cavaliers rookie Kevin Porter Jr. will undergo an MRI on his injured left knee Monday, league sources tell cleveland.com. While the Cavs left Rocket Mortgage FieldHouse feeling hopeful about Porter’s prognosis late Sunday night, they weren’t willing to rule anything out until they see the scans. Monday will determine the severity and timeline. “We’re bracing for some real time off,” a source said.
