(CBS) Bears receiver Brandon Marshall expressed no regret for his leading role in a postgame locker room shouting match after Sunday’s 27-14 loss to the Dolphins.

“Absolutely my voice was heard,” Marshall said during his weekly appearance on Showtime’s Inside the NFL. “The only thing I regret is that the door wasn’t closed. I wouldn’t change any of my reactions, because they came from my heart and that’s how I felt and that’s how I still feel.

“I think we have all the coaches we need. I think we have all the players that we need to get the job done. And 3-4 is unacceptable, but we have everything that we need to turn this ship right now.”

After Chicago lost Sunday, media members heard Marshall and other players shouting at one another through the closed doors before interviews began. One report indicated Marshall called out quarterback Jay Cutler, while other suggested he was just venting at the whole team.

For his part, Marshall called his relationship with Cutler “great” and that the the two good friends have a relationship in which they can be open about problems with one another.

In another take on the postgame fireworks, Bears linebacker Lance Briggs — who sat out Sunday’s loss with a rib injury — said he left the locker room after he heard the arguing start, but he didn’t think it was anything out of the ordinary.

“I understand being emotional and upset after games, and a lot of us are,” Briggs said on his weekly show on CSN Chicago.

“He’s certainly right about that. We have too much talent on this team … to have the record that we have.

“For me, it’s kind of hard to fathom.”
