Atlanta Falcons coach Mike Smith is expected to return to Atlanta on Sunday night after being examined in a Charlotte hospital.
The Falcons said in a statement that Smith was examined for a "non-emergency matter" but did not release details.
Atlanta general manager Thomas Dimitroff told Peter King of Sports Illustrated and NBC that Smith did not have a heart attack. Falcons spokesman Reggie Roberts would not confirm Smith was examined for chest discomfort.
Smith became ill and walked off the team plane after the Falcons' 31-23 win at Carolina on Sunday.
The Falcons say tests "reaffirmed his health."
Smith's status for the team's short work week before Thursday night's home game against Jacksonville was not known.
The 52-year-old Smith is in his fourth season with the Falcons.
