An MRI on the left knee of New Orleans Pelicans All-Star big man Anthony Davis came back negative, coach Alvin Gentry said after the team's 103-93 loss to the Trail Blazers on Tuesday night in Portland, Oregon. Davis is considered day-to-day, a league source told ESPN's Adrian Wojnarowski. Davis exited just five minutes into the first quarter, thought it's unclear when exactly he got hurt. He appeared to tweak the knee battling for position with Portland forward Maurice Harkless, then seemed to aggravate it while going after a long rebound with Trail Blazers guard Damian Lillard. Davis slowly ran down the court after the mild collision with Lillard and left the game during the Pelicans' ensuing possession. The Pelicans later said Davis would not return.
