The Broncos lost to the Colts, 29-28, at Lucas Oil Stadium on Sunday.

Here are three takeaways from the road defeat.

Surtain injury scare

Cornerback Pat Surtain suffered an ankle injury in the second quarter. It took place with about eight minutes left in the second quarter, and Denver was leading 14-13. The reigning NFL Defensive Player of the Year held his left leg in pain and went into the sideline medical tent for several minutes. But he missed only one defensive snap. Surtain returned with a heavily taped ankle for the next series. Defensive end Zach Allen also went down in pain in the first quarter. However, just like Surtain, he returned to play a short time later. The Broncos showed a lot of toughness on defense.
