Unclear where the breakdown in communication was here, but I’m told there was no such letter from the #Vikings to Griffen and his agent. The team did tell him to focus on his personal situation for the weekend. Mike Zimmer said today Griffen wasn’t playing anyway because of knee. https://t.co/5lPCqb0U8u
