Deion Sanders says that he has not yet been contacted by the NFL about the Michael Crabtree tampering investigation. However, in an interview with the NFL Network, Sanders said that he will tell the truth if questioned. The truth, Sanders claims, is that he has no knowledge of any tampering by the Jets in the 49ers' negotiations with the wide receiver. On Sept. 4, Sanders said on the NFL Network that two teams were willing to pay then-holdout Crabtree at least $40 million.
