MANKATO, Minn. — Vikings quarterback Taylor Heinicke will miss the start of training camp because of a leg injury suffered in what he called “a freak accident” 2 1/2 weeks ago at his home in the Atlanta area.

Heinicke said he suffered a cut above his left ankle that required surgery while trying to break into his own house. He’s hoping to be healthy by the Sept. 11 regular-season opener at Tennessee.

The third-string quarterback behind Teddy Bridgewater and Shaun Hill, Heinicke didn’t get into any games as a rookie last season.

“I was locked out of my house after a late-night movie,’’ Heinicke said. “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.”

Heinicke, who reported Thursday at Minnesota State Mankato with his foot in a cast, joked that at least the movie, “The Conjuring 2,” was “pretty good.’’

When asked about Heinicke, head coach Mike Zimmer declined to offer details but said he’s satisfied with the team’s current quarterback situation. The Vikings also have undrafted rookie free agent Joel Stave in camp.

A source said Heinicke at least will be back at some point during the regular season.

“We’re hoping for a speedy recovery,” Heinicke said, “so we’ll see what happens.”
