Denver Broncos' linebacker Dre Greenlaw has his choice of teams in free agency, but he chose the Denver for a particular reason that took him back to his childhood.

Linebacker Dre Greenlaw pulled up while covering running back J.K. Dobbins in a 1-on-1 drill Thursday, then jogged off the field with the Denver Broncos' athletic trainers and didn't return to practice.

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.
