Sapp posted a picture of the lobster catch on Twitter Wednesday along with a note, “Shark got a little chuck of Me. We got Dinner! (hash)Winning.”

Sapp is an all-time favorite among Raiders fans. He joined the Raiders in 2004 after playing several years with the Tampa Bay Bucs, signing a seven-year, $36.6 million contract.

After splitting his time between defensive end and defensive tackle in his first season in Oakland, Sapp regained his form and was an All-Pro in 2006. He retired from the NFL as a Raider in 2008.
