After admitting last week that LeBron’s decision to leave Cleveland caused him mental anguish, Mo Williams suffered some physical anguish, too. Courtesy of Boston.com: “Cleveland’s star point guard, who admitted being hurt by LeBron James’ decision to leave the Cavaliers, injured his right groin Friday while playing at the team’s facility and is expected to be limited for several weeks in training camp. The team said Williams ‘experienced right groin pain’ on Friday during a workout at Cleveland Clinic Courts, the team’s suburban training facility. After being examined by Dr. Richard Parker, Williams underwent an MRI that revealed inflammation but no tear. Williams will begin immediate rehab and treatment. The Cavaliers, who will open camp on Tuesday without James for the first time in eight seasons, expect Williams to participate in low-impact activities next week but don’t think he’ll be at full speed until mid-October.”
