ENGLEWOOD, Colo. -- **Defensive end Adam Gotsis returned to practice Friday after missing the previous two days because of an ankle injury and is one of six Broncos listed as questionable for Sunday's game with the Raiders.
Joining Gotsis among the players listed as questionable are nose tackle Domata Peko Sr. (illness), outside linebacker Shane Ray (wrist/ankle), wide receiver Emmanuel Sanders (ankle) and tight end Jeff Heuerman (knee).
Peko was the only one of that quintet who did not practice Friday. He was sent home because of what Head Coach Vance Joseph said was a "stomach bug," but he is expected to play against the Raiders.
Cornerback Aqib Talib, who sat out practice Wednesday because of a shoulder issue but returned to practice Thursday, was not listed as questionable and is expected to play in Oakland.
