Dulcich (hamstring) was a limited participant in Tuesday's walkthrough, Aric DiLilla of the team's official site reports.
The 21-day practice window for Dulcich to return from injured reserve opened just two days before Thursday's game against Kansas City, making it unlikely he'll be active for that contest. That said, coach Sean Payton told Parker Gabriel of The Denver Post that the tight end was close to gaining clearance to suit up. Dulcich will have one more chance to prove the health of his hamstring before the Broncos determine his availability for Week 6.
