Kelly left Sunday's practice with the injury. Coach Chuck Pagano is expected to provide an update Monday morning.

ANDERSON (WTHR) – Colts rookie center Ryan Kelly did not complete Sunday’s training camp practice. The first round draft pick out of Alabama suffered an apparent shoulder injury. Kelly’s shoulder was wrapped by trainers, but he stayed on the field, observing the rest of the workout. By the end of practice, Kelly did not have the shoulder wrapped and appeared to be in no discomfort as he talked with family visiting from his hometown of West Chester, Ohio. Colts spokesmen said the injury was nothing serious. Head Coach Chuck Pagano is expected to provide an update Monday morning.

The Colts enjoyed an otherwise beautiful Sunday for their first weekend workout of training camp at Anderson University. 4,258 fans watched in the stands, the biggest crowd in four days of practice.

The Colts begin their first game week of the preseason. The team plays five preseason games, starting next Sunday in Canton, Ohio, when they play the Green Bay Packers in the Hall of Fame game (8:00 p.m. ESPN). On Saturday, former Colts coach Tony Dungy and wide receiver Marvin Harrison are inducted into the Pro Football Hall of Fame.

The Colts have two new coordinators this season. Offensive coordinator Rob Chudzinski took over the roll mid-season last year after Pep Hamilton was fired. Now he can truly install his own offensive scheme.

“The biggest thing is that the guys have been gone for two months,” said Chudzinski. “We’re all the same way. I can’t remember what my wife told me a couple days ago and you’re asking these guys to recall on things that they were doing a couple months ago. It felt pretty good where we’re at. It’s obvious to me and I’m pleased. They did some work. They’ve worked out, they’re in shape. They’re in good football shape. We certainly have a long ways to go and we have a lot of things to get better at, but they put some work in over the summer time and it was good recall.”

New defensive coordinator Ted Monachino joined the Colts from Baltimore, where he coached the Ravens linebackers the past six seasons. Monachino is pleased with the effort from his defense.

“I think pleased is fair,” said Monachino. “Satisfied is absolutely not. Where I am at right now, we’ve got a long ways to go. The one thing we did on Friday is we all bought all the way into the technique and to the idea of championship effort and the idea of playing together as a team. We made just as many mistakes as we did the days before, but we made them all full-speed and when you make mistakes full-speed they cover up some of those things. I think that where we are right now is exactly where we should be. There are a lot of things that we need to clean up and we’ll do that each day in meetings and each day in practice.”

The Colts head to the Hall of Fame this week, and kicker Adam Vinatieri may be headed there whenever he finally retires. Vinatieri begins his 21st season in the NFL at the age of 43.

“Preseason is kind of that evil necessity,” said Vinatieri. “It’s good to be here. It’s good to get to work. You need the practice to get ready for the season but we all look for that Detroit (season opening) day. We have that circled on the calendar. It’s a long process to get us to that point and ready to go but looking forward to the regular season for sure.”

The Colts offensive line appears set at four positions, with Anthony Castonzo at left tackle, Jack Mewhort at right guard, Ryan Kelly at center and Joe Reitz at right tackle. Right guard is the position up for grabs. Hugh Thornton appears to be the front runner.

“Obviously every player wants to be a starter but I’m here to help the Colts win a championship,” said Thornton, in his 4th season out of Illinois. “So whatever they need me to do I’m here to fill that role.”

Thornton said he has dropped 27 pounds from last season, reporting to training camp at 313 pounds.

“I don’t know how many of you guys have been big, but being big is not an easy job,” Thornton said with a laugh. “I just wanted to slim down a little bit so that it’s easier on the joints for longevity in the league and just to feel healthier.”
