WESTFIELD, Ind. – Andrew Luck’s summer isn’t progressing as he had hoped or expected.

After handling a scaled-down workload during the first week of training camp, the Indianapolis Colts’ veteran quarterback missed Tuesday morning’s practice and won’t practice Wednesday or Thursday.

Blame a persistent strained left calf, an injury he first sustained in April.

“You could say a setback,’’ Luck said Tuesday. “I’d like to view it not (being) where I want to be.’’

He practiced three times last week, but never in full-go, team situations. The initial plan was for him to practice at some level Tuesday following the players’ day off Monday.

Instead, he came away with nagging pain in the calf.

“I did not improve feeling-wise, pain-wise,’’ Luck said. “And this is something that I vowed to myself after going through 2016 and 2017 that I would be, one, honest with myself about how I felt pain-wise with things (and) two, honest with the parties involved, Chris (Ballard), Frank (Reich), the medical staff, whomever.

“Then must make sure we took the time to make good decisions going forward.’’

Luck, who missed the 2017 because of his right shoulder, revealed he has had a magnetic resonance imaging (MRI) and X-rays to determine the nature and severity of the injury. He and the team have indicated it was a minor injury from the outset, but we’re now nearly three months into the rehab process.

Luck initially vowed he’d be ready to go full-go when camp opened.

“I did a disservice to myself saying I’d be ready,’’ he said. “That’s another thing I tried to learn with an injury. You can’t (predict). Bodies don’t care about a date on a calendar.

“That nature of it is a calf strain. I say lower leg because I feel pain in my ankle area.’’

His Achilles “is not at extra risk,’’ Luck insisted. “There is no tear or swelling or anything that’s indicated. It’s a calf strain.

“We’re on our feet a lot and for me to be the best quarterback I need to be to help this team the way I want to help them, I’m not looking for average.’’

Reich is attempting to keep things in perspective.

He insisted there is a chance Luck would be practicing and ready to play “if Sunday was a big game.’’

“We’ve still got plenty of time to go,’’ he said. “I was optimistic we could get through (last week’s four practices) and just keep going, but you feel what you feel. We’ve got respect that.’’

It already had been determined Luck would not play in the Aug. 8 preseason opener at Buffalo or the Aug. 29 closer at Cincinnati. It remains uncertain if he’ll play in game 2 against Cleveland (Aug. 17) or game 3 against Chicago (Aug. 24). Both of those are at Lucas Oil Stadium.
