Broncos interim coach Eric Studesville said he doesn't know whether kicker Matt Prater will be available for Sunday's game. Prater, who has a groin injury, did not make the trip to Arizona last weekend.
"He hasn't really done anything the last week as far as kicking," Studesville said. "It's been all rehab for him."
Prater was scheduled to attempt a few kicks during Thursday's practice.
The Broncos last weekend signed Steve Hauschka, who was 2-for-3 in field-goal attempts in the loss to the Cardinals.
