NHL teams will play 3-on-3 OT at least 3 times in preseason

There will be plenty of three-on-three hockey during the NHL preseason.

Before the league goes to five minutes of three-on-three overtime when it counts, 45 exhibition games will feature the experiment so that every team gets a chance to play it at least three times regardless of the score.

The Florida Panthers and Nashville Predators will get things under way Sunday night in the second game of their split-squad doubleheader. No matter the score, the teams will begin a five-minute, three-on-three overtime.
