A steady rain during the second half of Friday's joint practice with the Colts in Westfield, Ind., gave the workout a little more flavor.

Dealing with wet conditions is something the Ravens could face often during the regular season. There is just one indoor game on their schedule – Week 13 against the Atlanta Falcons at Mercedes-Benz Stadium.

Head Coach John Harbaugh was pleased with how his players dealt with Friday's slick conditions. Footing was a little dicey and the ball was slippery, but the Ravens' offensive execution remained crisp.

"It was good for ball-handling," said Harbugh. "You got to play in the North Atlantic. This is a good day for us to have. We haven't really had a rain day yet. It was pouring so hard back in Baltimore, we had to go inside the one or two times with the lightning."

While the Ravens' offensive players focused on securing the football, defensive players focused on taking it away. It was a solid day for the Ravens' defense getting reps against Colts starting quarterback Andrew Luck, one of the NFL's best players.

Luck is taking every practice very seriously, coming off shoulder surgery that forced him to miss the entire 2017 season. However, the Ravens' defense made several impressive plays against Luck, including a near pick-six by linebacker Albert McClellan, who dropped one of Luck's passes after controlling it momentarily.

The Ravens' goal in these joint practices is to leave Indiana a better team than when they arrived. Friday was a good first step.
