The Edmonton Oilers activated Mathieu Roy and sent him to the AHL for a “conditioning stint” today. I think Roy has probably earned a return ticket based on his play over the last few months, and he does have some strengths this team needs (strength, grit, plus shot).
When Souray gets back, the Oilers top 4D could easily be Pitkanen, Staios, Souray and Gilbert. Which leaves Tarnstrom, Grebeshkov, Smid and Rourke battling with Roy for the 5-7 slots.
A decent guess would be Pitkanen-Gilbert, Souray-Staios, Tarnstrom-Grebeshkov and Roy being the chosen 7 until Greene gets back from his injury.
Which means Smid and Rourke back to the A.
