Miami Heat point guard Mario Chalmers tore a tendon in his left ring finger last night in Washington, which could end sidelining him for up to five games. Reports the Sun-Sentinel: “Chalmers tore a tendon and will be out at least seven to 10 days, according to a source. The injury occurred in the first half of the Heat’s 105-101 loss. Chalmers was taken to the locker room, returning for the second half with his finger in a splint. ‘I caught a pass,’ Chalmers said after the game. ‘Somehow my finger got caught in the ball.’ The Heat did not practice Wednesday, but Chalmers said he would be further evaluated by team doctors. [...] The injury could leave the Heat thin at point guard. Norris Cole did not play against the Wizards because of a groin strain. His status is day-to-day. If Cole is unable to suit up versus the New York Knicks Thursday, the Heat will turn to LeBron James and Dwyane Wade as primary ball-handlers.”
