Butler has an illness, according to the team. Gronkowski remains in concussion protocol.
Butler, the star of Super Bowl XLIX with his late interception of Russell Wilson, becomes a free agent after this season. He talked last week about the possibility of Super Bowl LII being his last game in a Patriots uniform.
“Yeah, it crossed my mind,” Butler said, via Jeff Howe of the Boston Herald. “But you know what, man, the only thing that matters is doing whatever I can to help the team win this last game of the season. This is the biggest game of the season. I’ve got to put all [the contract ramifications] in the drawer. That’s not important right now. Over the years, I learned that it isn’t always about you. It’s about the team. Whatever is best for the team, I’ve got to do. [The contract] is not even important right now. I just want to win this championship. Just got to win, man.”
