Brett Favre will play for the Vikings on Friday in their preseason game against the Chiefs. Favre's mother, Bonita, told the Kansas City Star that her son will in fact debut just three days after signing with Minnesota. "He is going," Mrs. Favre said. "I have mixed emotions, but I have always loved to watch him play. This time, however, I thought he would stay retired and stay home. I guess he could not do it. "He told me he would always wonder 'what if?' I told him I supported him."
