The Miami Dolphins are signing former Minnesota Vikings wide receiver Greg Jennings, according to a source. He's previously visited the Dolphins, Jacksonville Jaguars, Carolina Panthers and New Orleans Saints, according to a league source. The Vikings cut him after they traded for wide receiver Mike Wallace. Jennings had 127 catches and 1,546 yards in two seasons and couldn't reach agreement on a restructured contract. Jennings had a five-year, $45 million deal with the Vikings, but lasted only two years with them. The Vikings saved $5 million against the salary cap.
