Shams Charania of Yahoo Sports reports that X-rays on Butler's right knee came back negative, and the team confirmed that he will have an MRI on Saturday. Minnesota Timberwolves forward Jimmy Butler was helped off the court during Friday night's game against the Houston Rockets after suffering an apparent right leg injury. Rockets center Nene landed on Butler's leg earlier in the play, but Butler appeared to hurt himself while trying to plant with his right leg seconds later.
