Andrew Luck working his way back from season of injuries

Indianapolis Colts quarterback Andrew Luck said Monday that he's still working to get back into healthy football shape.

Luck is coming off a 2015 season in which he missed nine games because of a lacerated kidney and rib, shoulder and abdominal injuries. His season ended against Denver in Week 9, when he suffered the kidney injury on a scramble play early in the fourth quarter. Luck remained in the game after getting injured, and the team announced two days later he would be out an extended period of time.

"I still l have some work to do, certainly," Luck said during the team's first day of offseason workouts. "You're always working to feel better. You're always working to be in better shape, to be more physically fit, so that's still a process. It's been a process that we laid down basically that first week after the season ended with our trainers and [physical therapists], the coaches and myself. We said, 'All right, here's the plan. Here's the plan basically until training camp starts, and let's follow this plan.' It's been a great plan so far. I feel really, really good."

Luck was vague on Monday in talking about where he is exactly healthwise. When asked whether he'll have any limitations once he starts throwing, the quarterback said jokingly, "I don't have to answer that question now because we're not on the field. I wish I had a crystal ball and had all the answers for you."

Colts owner Jim Irsay and coach Chuck Pagano both said during the NFL's annual owners meetings last month that Luck has to do a better job protecting himself. They feel he takes too many unnecessary hits because of his competitive nature, often trying to extend plays instead of sliding or throwing the ball away.

Luck, whom the Colts hope to sign to a long-term contract extension that totals more than $100 million by July 4, is coming off the least productive season of his four-year career. He threw for 1,881 yards, 15 touchdowns and 12 interceptions in seven games.

"You're always looking at self-evaluating after a season, but there definitely were some things last year that affect how I approach this year mentally, physically, emotionally in a sense," Luck said. "It started with a good training offseason before this and it'll continue now."
