Andrew Luck came out of Monday night's preseason game between the Indianapolis Colts and Baltimore Ravens "very encouraged."

It was just his second game in 19 months. The Colts' offense sputtered in their first five series in the 20-19 loss at Lucas Oil Stadium.

"I told someone after the game, 'I'm sort of happy to get sacked by [Terrell] Suggs, a legit sack,'" Luck said. "I landed on my right elbow sort of reminiscent of how I injured my shoulder a couple of years ago [in Week 3 of the 2015 season]. I didn't feel anything. Didn't give it a second thought. That's a big deal for me, being able to lose that thought bubble."

Luck was 6-of-13 passing for 50 yards, with an interception along with being sacked twice in 23 plays.

The first-team offense gained a total of 44 yards. Luck referred to their performance as being "sloppy" several times during his postgame media session.

"We turned the ball over, [and] my experience tells me that protection at times was not great," Frank Reich said. "We just didn't find a rhythm for him. I felt maybe there were one or two throws that weren't his best throws, but overall, it's usually not as bad as you think or as good as you think. Still have a confidence in a direction we're headed offensively."
