PITTSBURGH (AP) The Pittsburgh Steelers are united heading into the 2020 season. Yet even with every member of his team opting to play this fall, that doesn't mean Mike Tomlin is certain his club - or the NFL at large - will be able to navigate without any complications the next five months in the middle of a pandemic.

Asked on Thursday about his confidence level in the league avoiding what's happened to Major League Baseball - which now has enacted stricter measures designed to stem the spread of COVID-19 - the NFL's third-longest tenured head coach offered a blunt assessment.

"I don't know that I'm extremely confident," Tomlin said. "I respect the challenges that these circumstances have presented to other leagues, some of which we're witnessing. I think we're all proceeding with caution and working extremely hard not to become part of that. ... We're working our tails off to adhere to it and hoping that is enough, coupled with, obviously, personal decision making that needs to be exhibited continually by our guys throughout the course of this."
