The Vikings declined to comment about allegations that they made inappropriate contact with Brett Favre.  Vikings spokesman Bob Hagan released a two-sentence statement on Thursday saying they are not commenting on the issue, and that these types of matters are handled by the NFL.  Fox Sports reported on Wednesday that the Packers filed tampering charges with the league office against the Vikings for alleged communication with the retired Favre.  According to the report, Favre had inappropriate dialogue with Vikings offensive coordinator Darrell Bevell.  If the Vikings are found guilty of tampering by the league, they could be fined or lose draft picks.
