At the start of training camp, Indianapolis Colts quarterback Andrew Luck was sidelined with a calf injury, an issue that initially sprung up in April and reared its head again this summer.

But apparently, that isn’t the only injury Luck has been dealing with, as Colts owner Jim Irsay revealed earlier this week that Luck had a “small little bone” injury that turned out to be an ankle sprain.

So, how did Luck sustain the injury?

Indianapolis general manager Chris Ballard says the injury did not happen at any one particular time.

“I think it’s a cumulative thing, through the years,” Ballard said, per Michael David Smith of Pro Football Talk. “Andrew’s had some ankle issues with his left one for a while, and I think it’s just kind of a cumulative thing.”

Essentially, Ballard is saying that Luck’s injury is a result of wear and tear, which is somewhat concerning for a 29-year-old.

Ballard added that the Colts tried to give Luck treatment for the issue back in May, but it was unsuccessful.

As for Luck’s status moving forward, the signal-caller is not surprisingly not expected to play in the preseason, and his status for Week 1 of the regular season is very much up in the air.

This likely brings back memories of the summer of 2017 for Indy fans, as Luck was recovering from shoulder surgery and was originally expected to be ready early in the season but ended up missing the entire 2017 campaign.

Obviously, if Lucky is not 100 percent, it would be a severe—if not fatal—blow to the Colts’ Super Bowl hopes heading into 2019.
