Andrew Luck acknowledged his lackluster performance.
He played "not very well, but it was fun," Luck said Monday night on the ESPN broadcast after leading five series against the Baltimore Ravens.
Luck completed 6-of-13 passes for 50 yards. He also threw a red-zone interception and was sacked twice. His rating was 24.5. The Colts had 13 rushing yards on those drives.
Luck's best drive resulted in Adam Vinatieri's 57-yard field goal in the first quarter.
Luck noted his interception as a concern.
"Certainly we've got a lot of things to work on as a team and I've got a lot of things work on," he said.
