Tebow made his first career start Sunday against Oakland, passing for 138 yards and a touchdown and rushing for 78 yards and another score in Denver's 39-23 loss.
That was good enough to earn the former Heisman Trophy winner another go this week against Houston, Studesville told reporters.
"I thought Tim played well in his first start in a difficult environment," he said. "He really managed everything well."
Orton is still recovering from bruised ribs, making the decision to start Tebow an easier one than last week, when he wasn't tapped as the starter until just before game time, Studesville said.
