Posted in The Minnesota Vikings and center John Sullivan have agreed on a five-year extension, Tom Pelissero of 1500ESPN.com reports.
According to Pelissero, the extension is worth $25 million with $10 million guaranteed.
A sixth-round pick out of Notre Dame in 2008, Sullivan sat behind Matt Birk for a season before assuming the starting job in 2009. Sullivan has started 42 games over the last three seasons and was scheduled to become an unrestricted free agent in 2012.

highlight of the year?
Glad we locked him up but I can’t help but think were over paying.
Completely agree. Glad to see him back because he did improve this season under a new line coach, but I would have been firm around $18-20 million. I think they’re 3 for 3 on overpaying their own players this year. Peterson’s deal is the only one that I can understand it on because a guy like Snyder would have given him the same type of funny money, but I don’t think there is any chance another team would have given either Greenway or Sullivan the deals the Vikes came up with.
