There's been a Plaxico Burress sighting in a somewhat surprising capacity.

The former Giants wide receiver and Super Bowl XLII hero was on hand Friday in Glendale, Ariz., as the Cardinals opened training camp, according to multiple reports. Burress is said to be there as a coaching intern under head coach Bruce Arians, who was his position coach with the Steelers in 2004.

It's the first immediately known sign Burress may have an interest in coaching. Burress hasn't played in the NFL since 2012, when he had a stint with Pittsburgh, his first team, before retiring.

Burress played four seasons with the Giants, helping them win the third world title in franchise history when his late touchdown catch lifted them to a 17-14 win over the then-undefeated Patriots in the Super Bowl. His time with the team ended in disgrace when his self-inflicted gunshot wound at a Manhattan nightclub in 2008 led to a prison sentence and two years out of the NFL. He returned to play the 2011 season with the Jets before ending his career the next year.

One of Burress' old Giants teammates, former linebacker Antonio Pierce, worked with the Giants as a coaching intern during the offseason program.
