Around this time we see reports from training camp regarding injuries sustained on the field, but Vikings backup quarterback Taylor Heinicke found a way to get injured off of it.

Heinicke showed up to camp wearing a cast, and rolling around on a scooter, which prompted questions about how he sustained the injury. The second-year undrafted quarterback explained how he hurt himself, and he admitted he was embarrassed by how it went down.

"I was locked out of my house after a late-night movie,’’ Heinicke said, via the Minneapolis Star-Tribune. “I came back and there’s no one home, and I’m trying to nudge the door a little. It was one of those double doors. I thought it just needed a little nudge.

“Me and my buddy were getting it going a little, but when I put my foot to the door, my foot kind of slipped and it went through a window. It was just kind of a freak accident. I’m very embarrassed, but I’m just excited getting going with rehab and trying to get this going as soon as possible.”

The "freak accident," as he put it, took place 2 1/2 weeks ago, and he hopes to be ready for the Sept. 11 regular-season opener. The team didn't release any details about the injury, but ESPN reports he severed a tendon in his left foot, which could keep him out for up to three months.

Heinicke's stock was rising before the injury, and he was someone the Vikings believed could take the No. 2 spot behind starter Teddy Bridgewater.
