The Kansas City Chiefs have announced that they have placed the franchise tag on linebacker Justin Houston.
Despite Houston's level of displays for the Chiefs, the two parties have been unable to come to an agreement over a long-term contract, meaning that he will play the 2015 season out on the tag worth $13.195m (£8.5m).
"Justin is a talented player and a key contributor to our defense," general manager John Dorsey told the club's official website.
"Today was the deadline to designate a franchise player, and it was in the best interest of the club to place the tag on Justin.
"We will continue to discuss long-term options with him and his agent. Our goal is to reach a deal that is mutually beneficial. We want to keep Justin in a Chiefs uniform for years to come."
Houston has recorded 235 tackles, 48.5 sacks and one interception in his four years in the NFL.
