Denver's first player to land on injured reserve this summer is undrafted outside linebacker Johnny Walker, who will go on season-ending IR with a lower body injury. To fill Walker's former spot on the active roster, the Broncos signed UFL pass rusher Garrett Nelson.

The Denver Broncos believe linebacker Dre Greenlaw's latest injury isn't serious. Greenlaw pulled up while covering running back J.K.

Two days after backup linebacker Drew Sanders suffered a foot injury that is expected to sideline him for north of four to six weeks, starting linebacker Alex Singleton broke his thumb during Monday's training camp practice.
