The fire broke out around 3 a.m. in the kitchen of Wilson’s home in Seven Fields, about 30 minutes north of the city, according to authorities. Flames were visible to firefighters when they arrived on the scene, according to Cranberry Township director of Public Safety Jeffrey Schueler.
The 50-year-old Wilson, in his fifth season with the Steelers, was taken to a hospital before being airlifted to UPMC Mercy Hospital for treatment.
His condition was not immediately available. The cause of the fire has not been determined and remains under investigation.
Wilson will not travel with the team on Sunday when the Steelers face Denver in the first round of the AFC playoffs. Offensive assistant Harold Goodwin worked with the running backs during Friday’s practice.
Steelers president Art Rooney II said he was “saddened” by the news.
“We know that he has the best medical care in the country treating him,” Rooney said in a statement posted on the team’s website. “The entire organization is praying for Kirby to have a full recovery and we will be by his side through this difficult time.”
