Narrative:
Air carrier X on an 8 mi final to runway 22L was cleared to land runway 22L. Air carrier Y checked on the frequency on a 9 mi final; his airspeed indicated 50 KTS faster. The tower controller canceled air carrier Y's approach clearance and turned him 30 degrees left for collision avoidance. This took place during a position relief briefing. The oncoming controller saw what was going on and said he would take the position from that point.
