Williams and Erin Marzouki at the Buffalo Niagara International Airport in March 2012
BUFFALO, NY-- Buffalo Bills defensive end Mario Williams is dealing with some off-the-field drama.
KTRK-TV in Houston reported last week that Williams filed suit Friday to get the 10-carat diamond back from ex-fiance Erin Marzouki.
The ring is reportedly worth $785,000.
The lawsuit alleges that Marzouki never intended to marry Williams and used the relationship as a means to get to plaintiff's money and acquire gifts.
Williams claims Marzouki broke off the engagement earlier this year.
Marzouki accompanied Williams to Buffalo in 2012 when he signed his contract to play for the Bills.
