Surfing through the last news reports out of Dallas, I noted that the Stars had yesterday recalled forward Toby Petersen but he'd have to pass through re-entry waivers.

Usually during the season a team can claim a player via re-entry waivers and only have to pick up half his remaining salary. However, there is an interesting twist to the rule after the trade deadline has passed.

As per Mike Heika of the Dallas Morning News:

The process involving re-entry waivers changes after the trade deadline, as a team can claim Petersen for half price and place him on their NHL roster, but they cannot play him in the regular season or in playoff games for the remainder of the season. That allows teams to make call-ups like this without much risk of losing a player.

Pretty much ensures that a team can safely recall a player via re-entry waivers without fear of losing him to another team from the day after the trade deadline to the end of the season and into the playoffs.

Just goes to show you learn something new about the CBA every day!
