The Montreal Canadiens have traded defenseman Justin Barron to the Nashville Predators in exchange for Alexandre Carrier. Carrier, 28, has struggled this season with a minus-14 rating but has shown potential in the past, including a strong rookie year. Barron, at 23, has played less consistently for Montreal, prompting the move as the Canadiens seek more proven talent.

With the NHL's holiday roster freeze approaching, both teams look to solidify their defensive lines for the remainder of the season.
