Doug Smith reports: “It’s all fun and games until someone hurts a knee. Raptors rookie forward Ed Davis sustained a “meniscal” injury to his right knee during a pickup game Wednesday night and the treatment options are still being determined. Davis was playing informally in Mississauga on Wednesday — a gathering started by the team’s younger players using social media outlets — when he landed the wrong way after a rebound and hurt himself. … The team did not disclose details of any treatment for Davis, which could run from rest to arthroscopic surgery. Toronto begins training camp at the Air Canada Centre on Sept. 28. While there was no indication the injury had anything to do with people not involved with professional basketball, the game was taking place away from the team’s practice facility — and training and medical staff. Generally, in the final two weeks before training camp, players use the team’s facilities to work out and scrimmage with teammates. Davis, a 6-foot-10, 215-pound 21-year-old, was taken 13th overall by the Raptors in June’s NBA draft.”
