In his first start since early November, Luck completed all eight of his passes, led the Colts on two long drives and avoided taking any hits in a 19-18 loss to Baltimore.
Sure, it's only preseason, but the Colts wanted to see which Luck would show up - the guy who went to Pro Bowls in each of his first three NFL seasons or the turnover-prone quarterback who couldn't stay on the field in 2015.
Luck was eager to come back, too, after seeing the Hall of Fame game cancelled two weeks ago and being benched in soggy Buffalo last week.
It didn't take him long to get in sync.
He opened the game by leading the Colts on a 61-yard drive that set up Adam Vinatieri for a short field goal. He had Indy in position to score again - until Dwayne Allen lost a fumble at the Baltimore 18-yard line. The final numbers: 8 of 8, 69 yards, no touchdowns, no interceptions, no sacks and two slides.
