This one’s really gotta hurt. Chicago Bulls point guard Derrick Rose tore his ACL on Saturday night in the opening game of the team’s first-round playoff series against the Philadelphia 76ers. The Bulls won the game 103-91, but are now outside contenders for the NBA title with the loss of their star player. The injury also almost guarantees Rose’s absence from the summer Olympics in London, to be played in July. Rose crumpled to the floor in the closing minutes of the Bulls’ win, exiting the court with a pained look on his face.
