INDIANAPOLIS, Ind. – Andrew Luck was limited in practice for a second day Thursday – his right shoulder is the culprit – but the Indianapolis Colts are doing their best to minimize the issue.

General manager Ryan Grigson has declined interview requests from the local media this week, but addressed Luck’s situation during a Thursday appearance on The Dan Dakich Show on 1070 The Fan. He indicated Luck’s limited status was a matter of maintenance.

“I mean it’s no different from other quarterbacks in the league that say they’re limited and they get rest just like Robert Mathis gets rest or other players,’’ Grigson said. “You just want guys fresh going into the season, and he’s in a new chapter, really, in this organization and on this team, and you just want the guy to be fresh for Sunday.’’

An internet report mentioned Luck has a “frayed labrum.’’ Grigson was quick to dismiss it.

“He’s all good,’’ he said. “I mean the guy’s thrown a zillion balls. The media’s seen it. (He was) in Anderson day-in and day-out throwing a ton of balls with a lot of velocity . . . I guess you could sit there and look for something that’s not there, but I’m just saying he’s going to be ready for the game this weekend and we have a plan that we think’s best for him and one he feels good about and that’s what we’re doing.’’

Prior to the afternoon practice, offensive coordinator Rob Chudzinski was asked if he expected Luck to play against the Detroit Lions.

“Absolutely,’’ he replied.

During the portion of Thursday’s practice open to the media, Luck worked with the running backs. He handed off and didn’t throw a pass. Backup Scott Tolzien threw to the receivers and tight ends.

Also seeing limited action Thursday were defensive end Kendall Langford (knee), defensive tackle Henry Anderson (knee), offensive tackle Joe Reitz (back), guard Jack Mewhort (knee), offensive lineman Joe Haeg (ankle) and linebacker Sio Moore (hamstring).

The limited participation of Mewhort and Haeg is an encouraging sign for the offensive line. One could be active for the Lions game.

Kelly rare rookie:

Ryan Kelly joined an exclusive group in April when the Colts selected him with the 18th overall pick in the NFL draft. He became just the ninth center taken in round 1 since 2000.

Sunday, Kelly will be the first Colts rookie to start at center on opening day since – wait for it – Jamie Richard in 2008. Jeff Saturday suffered a knee injury during the preseason that would keep him out of the first two games of the season.

That opened the door for Richard, a seventh-round draft, to snap for Peyton Manning on opening day. He would start the first two games until Saturday’s return.

Roster moves:

The Colts signed quarterback Stephen Morris to the practice squad and waived safety Lee Hightower. Morris survived the final cut when the team trimmed the roster to 53, but was waived Wednesday to make room for cornerback Rashaan Melvin.
