Vols coach Butch Jones tweeted a picture Saturday that showed a red arrowhead with the message "29 Strong VFL" and said it would be added to each player's helmet. Berry wears No. 29 for the Chiefs. The term "VFL" stands for "Vol For Life."
Berry went on the non-football injury list Monday after a mass was found on his chest that doctors believe could be lymphoma.
He starred for Tennessee from 2007-09 and won the 2009 Jim Thorpe Award as the nation's top defensive back.
