Okwuegbunam (ankle) was a limited participant during Thursday's practice, Zac Stevens of TheDNVR.com reports.
This is unfortunate news for Okwuegbunam, as he just resumed practicing after dealing with a hip problem during training camp. With second-year pro Noah Fant locked in as Denver's clear top tight end, Okwuegbunam's possible absence from the team Week 1 won't affect much from a fantasy perspective.
