Former National Football League quarterback Steve McNair and an unidentified woman were found dead Saturday.

Police said they were called to a home in Nashville's downtown area where the former Tennessee Titans and Baltimore Ravens quarterback and the woman were involved in a double shooting.

Police said they don't know the circumstances surrounding the shooting, including when it took place. They have identified the woman but are declining to release her name.

"We are saddened and shocked to hear the news of Steve McNair's passing today," Titans owner K.S. "Bud" Adams said.

"He was one of the finest players to play for our organization and one of the most beloved players by our fans.

"He played with unquestioned heart and leadership and led us to places that we had never reached, including our only Super Bowl. Our thoughts and prayers are with his family as they deal with his untimely passing."

A three-time Pro Bowl selection, McNair shared the most valuable player of the NFL award in 2003.

In 161 games (153 starts), McNair threw for 31,304 yards on 2,733- of-4,544 passing, with 174 touchdowns. He also ran for 3,590 career yards and 37 TDs.

McNair last played in the NFL in 2007 for the Ravens. He is a former third overall pick by Houston in the NFL's 1995 entry draft.
