I mean if you listed him as out for 2-3 weeks, does that not make him week to week?
No. Week to week is a longer term injury usually lasting 1.5 - 2 months or more.
Bear in mind I enter what the Oilers state the injury and the length of injury is, backed up by the direct link which I always post. I then update the status as new reports come it.
I am not making this stuff up. Just posting it for the forum members as a courtesy so they can see the injuries in one place easily.
