Wilma McNabb is proud of her son, Donovan, and she is not afraid to show it.

The mother of the former Eagles, Redskins and Vikings quarterback recently penned a tribute song to her son, and it is quite touching. In the song, titled "When Your Heart is on the Field," Wilma McNabb conveys the overwhelming joy she experiences from watching her son play.

Wilma McNabb wrote the lyrics while singer Tené Williams recorded the song. On the song's YouTube page, McNabb describes her motivation:

"This song has been ringing in my head for 13 years, while my son Donovan played as an NFL QB. As parents of an athlete you feel more than you see as you watch the game. Listen to the words, and I am sure you too will understand the emotions we get, when your heart is on the field."

Mama McNabb, the stage is all yours.
