The Minnesota Vikings, who upgraded their receiving corps with the addition of ex-Bear Bernard Berrian, maintained their depth at the position when Robert Ferguson accepted a one-year offer. The deal is worth about $1 million, and there are chances for him to make an additional $500,000 to $600,000 with incentives.  Ferguson, 28, went to the Vikings last season after being cut by the Green Bay Packers, where he had spent the first six years of his career.
