You think you had a crappy Valentine's Day ...
TMZ Sports has learned NFL legend Terrell Davis has been hit with divorce papers courtesy of his beauty queen wife ... who filed to end the marriage 3 days before Valentine's Day.
In docs filed in L.A. County Superior Court, Tamiko Nash -- the 2005 Miss California winner and former 'Price is Right' model -- cites irreconcilable differences after more than 5 years together.
