Broncos LB Dre Greenlaw (quad) did not practice on Thursday.

Greenlaw is trending toward missing Week 1 at this point, as he rehabs his second significant quad injury of the offseason. If he is active, it’s unlikely he plays a full complement of snaps. Broncos backup DT Malcolm Roach exited practice after suffering a calf injury today, which jeopardizes his availability for this weekend.
