EDEN PRAIRIE, Minn. — As long as Sam Bradford stays healthy this season, the Minnesota Vikings won’t be worried about their quarterback situation.

There’s a lot of uncertainty behind Bradford on the depth chart, though.

Teddy Bridgewater remains immersed in his rehabilitation program, of course, trying to push his knee back into playing shape. He’s on the physically unable to perform list, where he’ll likely start the regular season.

So if the Vikings decide to keep a third-stringer on the active roster behind Bradford and backup Case Keenum, they’re currently looking at Taylor Heinicke or Mitch Leidner.

Heinicke is the third-year project who went undrafted out of Old Dominion and has never taken a snap in an NFL regular-season game. He’s most famous for severing two tendons in his foot from an ill-fated kick through a glass pane of a door to his friend’s apartment that they were locked out of.

Leidner is the local rookie who signed with the team on Sunday. He’s the only player in Minnesota program history to rush (33) and pass (36) for 30-plus touchdowns in his career. Leidner was driving around meals for the restaurant delivery service Bite Squad in between workouts while waiting on a call from an NFL team.

Heinicke has had a spotty preseason. He sat out of practice on Sunday and Monday because of an injury. Leidner produced just three passing scores against 11 interceptions over eight Big Ten games in his senior year. The Vikings cut Wes Lunt, an undrafted prospect from Illinois, at the beginning of training camp.

The question, then, is whether they’ll reserve a 53-man roster spot for an unproven prospect at the position as long as Bridgewater is sidelined.

“I think it’s extremely important that you’re always developing quarterbacks,” offensive coordinator Pat Shurmur said.
