A player for the Baltimore Ravens football team is being praised for jumping in to help during a mid-flight medical emergency.
Mark Andrews, a tight end, reportedly rushed to assist flight attendants and healthcare professionals when a fellow passenger became ill.
The Ravens confirmed Mr Andrews' actions to the OceanNewsUK.
"The real heroes are the nurse and doctor who also happened to be on the plane," Mr Andrews said in a statement.
He also said the "fast-acting flight attendants" provided "the woman the quick assistance she needed".
The professional athlete was on a Thursday morning Southwest Airlines flight from Baltimore, Maryland to Phoenix, Arizona when a female passenger began experiencing medical issues.
The woman was "in and out of consciousness to some degree" and "not really being responsive," Andrew Spring, another passenger on the flight, told the local CBS News affiliate WJZ.
Seated just a few feet away, Mr Spring watched as flight attendants and a doctor and nurse who happened to be on the plane began to help the woman. Then Mr Andrews jumped in.
"'Do you know, could her blood sugar be low? I have a diabetic test kit,'" Mr Spring recalled the football star saying.
"So, Mark reached under his seat, pulled out his diabetic test kit," said Mr Spring.
Mr Spring vividly chronicled the entire episode on X.
In one post, he recounted how Mr Andrews "instructed the medical professionals…on using his test kit".
Southwest Airlines spokesman Dan Landson confirmed that medical personnel responded to the flight when it arrived in Phoenix, but declined to share further details, citing customer privacy concerns.
Mr Andrews was diagnosed with Type 1 diabetes at age nine, and according to the Ravens' website, "is an outspoken advocate for those with diabetes and is extremely vigilant about his self-care".
He frequently monitors his blood sugar during games, the Ravens wrote.
Though his team later posted on X about his quick actions, Mr Andrews deplaned with "no fanfare", Mr Spring wrote on Twitter.
"As he has done his whole career, he stepped up in a huge moment when people needed him most," he wrote. "Watching complete strangers spring into action to help save someone's life is truly amazing."
