Is Colton Parayko trade done? What Sabres are waiting for in Blues deal

The Buffalo Sabres are waiting. 

They've apparently agreed to a deal with the St. Louis Blues for defenseman Colton Parayko on Wednesday.

The trade hasn't been completed, though.

TSN's Darren Dreger reports that the Sabres would send prospect Radim Mrtka and a first-round pick back to St. Louis.

There's just one thing that's holding it up.

What are the Sabres waiting for?

Reportedly, Parayko has yet to waive his no-move clause.

A no-move clause is in a lot of veteran contracts and essentially allows them to dictate where, when and how they are traded.

If Parayko doesn't want to come to Buffalo, he can simply veto the move himself.

Is the Colton Parayko trade done?

As of 9:30 p.m. ET, there still haven't been any reports indicating that Parayko has approved the deal.

That doesn't mean it won't happen. It simply means it hasn't happened yet.

Sabres fans will be holding their breaths until they know the resolution here.
