Greg Bensel was the first to break the news via Twitter:
Saints agree to terms on a four-year deal with 4th round pick WR Nick Toon
Financial terms, of course, were not made available.
Toon played his college ball at the University of Wisconsin. He is the final Saints draft pick to be signed, which means the team now has all five rookies under contract, just in time for the start of training camp at the end of the month.
