ENGLEWOOD -- This is perfect for the Broncos.

Their quarterback Case Keenum has another challenge to overcome. This time it’s knee soreness from the game Sunday against the Oakland Raiders that held him out of practice Wednesday. Keenum scrambled three times in the fourth quarter Sunday and he got up slowly after his 7-yard scramble with about a minute to play.

“Yeah, I guess I need to slide a few more times instead trying to go run and bounce around off of defenders,'' Keenum said. "But I want to get a first down, I want to score. I’m competitive in that way.”

The knee soreness is considered mild -- he is expected to practice Thursday and play Sunday at Baltimore against the Ravens.

“Woke up on Monday a little sore,'' he said. "I could’ve practiced today, I wanted to practice, but they wouldn’t let me. So, a good mental day.”

The Broncos will need Keenum for their first road game Sunday against the Baltimore Ravens, especially in the fourth quarter.

There is a correlation between all the knocks he took early in his career and his ability to come through in the fourth quarter when all seemed lost in the Broncos' first two wins.

"I always see the tough times, the obstacles, I would say ,I see them as an opportunity to overcome,'' Keenum said. "I’ve had to look at that because I have had obstacles and have had adversity. But to have the ball in the fourth quarter, in your hands, with a chance to win a game — that happened a lot early in my career and it didn’t happen. It’s fun when it does and I cherish it when it happens. Those are exciting games to win.”
