Other players on the trip were Cleveland Browns offensive tackle Joe Thomas, Dallas Cowboys tight end Jason Witten and Houston Texans defensive end Mario Williams. Davis, formerly of the University of Maryland, said in a written statement released by the USO: "I've had a terrific experience on my USO tour. The troops have taught us so much, and it is amazing to see their courage and bravery."
