Humphrey was elevated from the Broncos' practice squad Saturday, Parker Gabriel of The Denver Post reports.
Humphrey was also called up to the active roster in Week 1, playing 21 snaps on offense and unable to reel in his lone target. With Devaughn Vele (ribs) out of action for Sunday's game against the Steelers, Humphrey may find himself with extra opportunities in the Week 2 matchup.
