The Indianapolis Colts are playing Sunday's game against the Tennessee Titans with a pair of quarterbacks signed off the street earlier this week, but you wouldn't know it based on the team's offensive output.

With the Colts trailing 14-13 late in the first half, quarterback Ryan Lindley found Andre Johnson for an incredible 18-yard touchdown reception. The 13-year veteran made the catch while falling at bounds, but was able to scrape the pylon with his foot, while extending the ball over the goal line for the score.

How does Andre Johnson stay in bounds and stretch out for this touchdown? It just doesn't make sense. #TENvsIND https://t.co/f0aN77rNPR
