The 29th would be 10 business days from now. I think that's what they go by.
I don't believe there is any time frame for when they have to reach a verdict on the appeal. The went 5 weeks without ruling on Brady's appeal.
I wonder how much time would be needed to go to court to get an injunction. I have seen a few legal opinions say that Elliott's attorneys are making a mistake not filing in court now. That by following the appeal process, Elliott is giving the league control over legal jurisdiction as well.
