According to a league source, the Kansas City Chiefs signed outside linebacker Cory Greenwood to a four-year contract extension earlier this week.
Signed in 2010 as an undrafted free agent out of Concordia University in Canada, Greenwood has been active for all of the Chiefs' 32 games over the last two seasons, totaling 24 tackles, including 21 on special teams. Greenwood led the Chiefs with 12 special teams tackles in 2011.
Greenwood was scheduled to be an exclusive rights free agent in 2012 and would not have been an unrestricted free agent until the 2014 offseason. Signed on January 3, the four-year extension is worth $2.75 million and has locked Greenwood up through the 2015 season.
Greenwood received a $25,000 signing bonus and is scheduled to earn base salaries of $540,000 (2012), $630,000 (2013), $730,000 (2014) and $745,000 (2015) with $20,000 workout bonuses available each season.
