Liam Reddox got an assist tonight against the Nashville Predators, but the more important thing for him was playing in the game at all.  This was Reddox's tenth game of the season, which means he now needs to clear waivers to get sent back to Oklahoma City.  Here's the relevant section of the CBA:

13.2 The "Playing Season Waiver Period" shall begin on the twelfth (12th) day prior to the start of the Regular Season and end on the day following the last day of a Club's Playing Season. Subject to the provisions of this Article, the rights to the services of a Player may be Loaned to a club of another league, upon fulfillment of the following conditions, except when elsewhere expressly prohibited:

(a) Regular Waivers were requested and cleared during the Playing Season Waiver Period; and

(b) the Player has not played in ten (10) or more NHL Games cumulative since Regular Waivers on him were last cleared, and more than thirty (30) days cumulative on an NHL roster have not passed since Regular Waivers on him were last cleared.

Given how well he's played with the Oilers since being called up, I think there's a pretty good chance that he'd get claimed should the Oilers try to send him back.  So congratulations, Liam!  You'll probably be earning an NHL paycheck for the rest of the season!
