Following the confirmation, Berry released a statement saying "I am truly thankful for all of the support from family, friends, coaches, teammates and the entire Chiefs kingdom.

At first I was in shock with the diagnosis on Saturday and did not even want to miss a game, but I understand that right now I have to concentrate on a new opponent.

I have great confidence in the doctors and the plan they are going to put in place for me to win this fight.

I know my coaches and teammates will hold things down here the rest of the season and until I am back running out of the tunnel at Arrowhead.
