Broncos coach Gary Kubiak experienced flu-like symptoms and was taken from the stadium to a hospital by ambulance after Denver's 23-16 home loss to Atlanta on Sunday.
Team spokesman Patrick Smyth said Kubiak was transported as a precaution about 45 minutes after the game.
Kubiak had a health scare in 2013 when he was Texans, coach suffering a "mini-stroke" in a frightening scene in which he collapsed at halftime during a game.
Kubiak said when he took the Denver job last year that he had learned to spread out the workload and pressure among his staff.
Ravens offense stuck in mud
Baltimore quarterback Joe Flacco spent much of Sunday frantically running from the pocket, and he had only one touchdown to show for it in a 16-10 home loss to Washington.
The Ravens, who have former Bears coach and Minnesota native Marc Trestman as their offensive coordinator, went three-and-out on four occasions, gained only 125 yards after halftime and were so ineffective offensively that even the home fans felt compelled to boo.
"It's frustrating. I'm not happy," Flacco said. "When you play like that, it's embarrassing to run off the field in front of your home fans, in front of your teammates."
Not the greatest shoes of all time
Steelers star receiver Antonio Brown planned to wear cleats honoring boxing great Muhammad Ali on Sunday, just as he did the week before in cleats that featured a sketch of golfer Arnold Palmer. However, Brown was told before kickoff he needed to switch shoes or face a fine.
