Former NFL star Michael Oher, whose inspirational life story became the subject of the Oscar-winning 2009 movie "The Blind Side," is suing the Tennessee couple who took him in as a teenager.

Oher, 37, who won a Super Bowl with the Baltimore Ravens during eight seasons in the NFL, alleged in a legal petition filed on Monday that Leigh Anne Tuohy and her husband Sean Tuohy tricked him into signing away control of his financial affairs.

Oher alleges in the filing that instead of being legally adopted by the Tuohys, as he was told, the Tuohys instead established a conservatorship which allowed them to profit from his name.
