The Edmonton Oilers have activated Oscar Klefbom off injured reserve, and to make room have waived Eric Gryba. Gryba wasn’t on waivers when they were reported earlier today, which means he’ll likely have to wait until Sunday to clear and be assigned to the minor leagues. It’s a tough break for Gryba, who hasn’t suited up in the AHL since 2012-13. The 29-year old defenseman has played 21 games for the Oilers this year, and could be an option for another team around the league.
