The Kansas City Chiefs have announced that safety Eric Berry will be out for the rest of the season for an illness not related to football.

After the Oakland game, Berry went to head coach Andy Reid and complained of a pain in his chest.  He underwent an MRI on Friday where a mass on the right side of Berry’s chest was discovered. Additional tests and blood work indicated the possibility Berry has lymphoma.

This afternoon, Berry released a statement through the team.

“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 believe that I am in God’s hands and I have great peace in that. 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. I am so thankful and appreciative of being a part of this franchise and playing in front of the best fans in the NFL. I will be back!”

Berry is 25 years old.
