Broncos' Jonas Griffith: Lands on injured reserve

Griffith (knee) was placed on IR on Thursday, Ben Swanson of the Broncos' official site reports.

Griffith suffered the injury during a special-teams drill Tuesday when he stepped on another player's foot. Mike Klis of 9News reported the severity of the injury earlier Thursday, so his official move to injured reserve doesn't come as a surprise. In Griffith's absence, the team signed linebacker Austin Ajiake.
