MANKATO, Minn. (AP) — The Minnesota Vikings have signed kicker Blair Walsh to a contract extension.

The new deal was done on Sunday, the first day of training camp for the team. Terms weren't disclosed.

Walsh was a sixth-round draft pick in 2012 out of Georgia entering the final year of his rookie contract. Walsh set an NFL record by making 12 consecutive field goals from 50-plus yards to start his career, 10 of which came in his first season. Since then, Walsh's productivity has fallen off, with a 74.3 percent field goal rate in 2014. He made 92.1 percent in 2012 and 86.7 percent in 2013.

Vikings place linebacker Casey Matthews on injured reserve

MANKATO, Minn. (AP) — The Minnesota Vikings have placed linebacker Casey Matthews on injured reserve, ending his first season with the team before it started.

Matthews, the younger brother of Green Bay Packers linebacker Clay Matthews, hurt his hip doing hurdles during offseason workouts and never made it on the field for practices with the team. Coach Mike Zimmer announced the news on Sunday.

Matthews was a fourth-round draft pick by Philadelphia in 2011 and played four years for the Eagles before signing a one-year contract with the Vikings. He likely would have been in the mix for the competition for time at middle linebacker.

The Vikings also placed cornerback Josh Robinson on the physically unable to perform list because of a torn pectoral muscle.
