NFL star McNair found shot dead
McNair led the Tennessee Titans to the Super Bowl
Recently retired American football star Steve McNair and an unnamed woman have been found shot dead in Nashville, Tennessee, police say.
"Air" McNair, who played 13 years with the National Football League and was a quarterback for the Tennessee Titans, had a gunshot wound to the head.
The two bodies were found in his flat in the city and police are treating the case as a double homicide.
Police say they believe they know the woman's identity but gave no details.
McNair led the Titans within a yard of forcing overtime in the 2000 Super Bowl, which they lost 23-16 to the St Louis Rams.
He also played for the Baltimore Ravens before retiring in April 2008 after injuries.
He was one of the finest players to play for our organisation and one of the most beloved players by our fans
"We don't know the details, but it is a terrible tragedy and our hearts go out to the families involved," NFL commissioner Roger Goodell said in a statement.
Titans owner Bud Adams was "saddened and shocked" by news of McNair's death.
"He was one of the finest players to play for our organisation and one of the most beloved players by our fans," he said.
"He played with unquestioned heart and leadership and led us to places that we had never reached, including our only Super Bowl."
