Manning visits just as Broncos cornerbacks Champ Bailey and Andre Goodman are hobbling.
In the Broncos' 31-14 victory Sunday against Seattle, Goodman limped off the field late in the third quarter with a thigh injury, and Bailey left the stadium on crutches with a bruised right ankle.
It could be worse.
"Nothing's broken," McDaniels said. "We're hopeful. We'll see how that goes. It would be an important game, obviously, to have those guys available."
Of the two, Bailey may have the better chance to play. Goodman appeared to have the type of pulled muscle that requires time to heal.
