NFL Authentic Game Ball signed by Minnesota Vikings punter #4 Chris Kluwe (signed when he wore jersey #5).

Chris Kluwe signed on with the Vikings as a punter in 2005. He became one of the most surprising pickups for the Vikings, finishing the season with an average of 44.1 yards per punt, ranking second in the NFC and sixth in the league. In Oct 2007 Kluwe signed an $8.3-million contract extension through 2013. The deal made Kluwe one of the 10 highest paid punters in the NFL.

In 2011 Kluwe changed his jersey number to #4 when the Vikings acquired quarterback Donovan McNabb. Kluwe took up the number which was previously worn by quarterback Brett Favre.

In addition to his full time job as punter for the Vikings, Kluwe is the bassist for the local Minneapolis Alternative/Progressive Rock band, Tripping Icarus. Chris formed the band in 2009 with some friends. 

When Donovan McNabb was traded to Minnesota, Kluwe offered McNabb the number 5 jersey in exchange for mentioning Tripping Icarus in at least 5 press conferences, as well as donating $5,000 to Kluwe's charity.
