"There is a sense of relief, for sure. We've had some tough losses," Frazier told reporters after the match.
"In the fourth quarter of every one of these ball games we were right there but for whatever reason it didn't work out for us so to come away with a win in the fashion that we did, this many miles away from home, knowing that we have what it takes to keep a team together after some of those losses.
"I'm just so proud of our coaches for getting those guys prepared, focused on the task in hand, not looking back just looking forward at Pittsburgh and how we could beat them. It was a great job by our players and a great job by our staff."
Meanwhile, the result leaves the Steelers still looking for their first win of the season as they fell to 0-4.
