The Carolina Panthers released injured offensive tackle Michael Oher on Thursday, just days after he was critical of Dave Gettleman's firing.

The move is the second by Marty Hurny since he was brought back in to fill the role of GM, via ESPN:

Panthers offensive tackle Michael Oher, who has been in the NFL concussion protocol since last September, was released Thursday after failing a physical.

It was the second move made by interim general manager Marty Hurney since being hired Wednesday. Earlier in the day, he gave right guard Trai Turner a four-year, $45 million extension with $20.45 million guaranteed.

In his criticism of the Gettleman firing, Oher also took shots at his teammates, saying, "Karma's a MF."

Following his release Oher tweeted, "The Brain is a scary thing. You have to be careful with it."

The Brain is a scary thing. You have to be careful with it.

That tweet was met with a ton of support, including fellow concussion sufferer Dale Earnhardt Jr.

Patience and stay the course. Pulling for you to get where you want to go.
