BUFFALO, N.Y. (AP) — Buffalo Bills defensive end Shawne Merriman is showing off his tattoos as a model for PETA to encourage people not to wear natural fur coats.

The animal rights group is unveiling an ad campaign Thursday featuring a photo of a bare-chested Merriman under the title: "Ink, Not Mink." The ad features the line: "Be Comfortable in Your Skin, and Let Animals Keep Theirs."

Merriman is noted for his numerous tattoos, including one on his chest with the words "Heart of Gold" prominently featured in the photo.

PETA has used other athletes in its campaigns, including current and former NFLers Willis McGahee, Tony Gonzalez and Michael Strahan.

Merriman, a three-time Pro Bowl selection, spent parts of the past three seasons with Buffalo. He's eligible to become a free agent this offseason.
