Blues forward Chris Porter has agreed to terms on a two-year, one-way contract extension, the club announced today.

Porter, who will turn 29 in May, was scheduled to become an unrestricted free agent this offseason.

The one-way deal is of much significance for Porter, an undrafted winger out of the University of North Dakota who was signed as a free agent in 2007. Over the past seven years, he has had four two-way agreements with the club, in which he makes a minor-league salary when assigned to Peoria of the American Hockey League.

Under his new contract, Porter will be guaranteed an NHL salary. The deal will pay him $650,000 in 2013-14 and $700,000 in 2014-15.
