Inside Edition's special Super Bowl correspondent caught up with the Wounded Warriors this week as they took on a team of former NFL and college players in a very special game ahead of Super Bowl Sunday.

One of the participants, Kirstie Ennis, lost a leg when her helicopter was shot down over Afghanistan in 2012.

"We’ve been through a lot and are finding that brotherhood again," she told Inside Edition.

Michael Smith, the first amputee to return to active service, added: "We've all protected and served. We've been knocked down but it’s not over."

Ennis and Smith took on a gridiron alumni team consisting of former quarterback Michael Vick and other players from the Houston Oilers, Dallas Cowboys, Texas A&M, UNLV and the University of Houston.

Biles also got a chance to meet fellow Olympic gold medalist Mary Lou Retton at the Wounded Warriors event.

Biles called her day with the Wounded Warriors "a humbling experience."
