Former NFL defensive lineman Esera Tavai Tuaolo has posed for the NOH8 Campaign, which supports gay rights causes, including ending California's gay marriage ban, Proposition 8.

Tuaolo announced in 2002 that he's gay on HBO's Real Sports after he retired from a 9-year career in the NFL.

The 42-year-old Tuaolo played college football at Oregon State University and was drafted by the NFL in 1991. He played with the Atlanta Falcons, Carolina Panthers, Jacksonville Jaguars, Minnesota Vikings and Green Bay Packers.

In 2006, he told NPR radio that he feared being outed while playing in the NFL: “One of the biggest fears that I was living with is that someone would see me on television and might out me. So everything that I worked so hard for since I was a little kid that would be all taken away or to support my family. Just because society didn't accept who I truly was.”

The NOH8 Campaign, which is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley, photographs celebrities and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

Tuaolo posed in his photograph wearing a white t-shirt and proudly displaying his 1999 Super Bowl ring.

This week, Carolina Panthers linebacker Nic Harris also joined the campaign.
