Denver Broncos defensive end Elvis Dumervil sat out Wednesday’s practice as he continues to recover from a left shoulder strain. But Dumervil is expected to try and practice either today or tomorrow and hopes to play in Sunday’s AFC West clash against the San Diego Chargers in Denver. Cornerback Tracy Porter also missed practice yesterday. He has yet to be cleared after experiencing pre-seizure symptoms last month. Back to practice on a limited basis for the Broncos are guard Chris Kuper, recovering from an ankle injury, and linebacker DJ Williams, returning from suspension.
