Three months after severing a tendon in his left foot in a freak home accident, quarterback Taylor Heinicke is ready to return to practice Wednesday for the Vikings.

Monday was the first day Heinicke was eligible to practice since being placed on the reserve non-football injury list Sept. 3, and he said he had expected to take the field. But Heinicke said general manager Rick Spielman told him before Monday’s workout that Wednesday instead would mark his return to practice.

“I’m confident I’ll be fine out there,’’ Heinicke said. “(The Vikings) did what they had to do to get me back to 100 percent, so I’m excited to get back out there and practice.’’ Related Articles Vikings coach Mike Zimmer on Faciane’s drunken driving arrest: ‘It was stupid’

After Heinicke takes the field, the Vikings will have 21 days to decide whether to place him on the 53-man roster or leave him on the NFI list for the remainder of the season.

Because Monday’s was a light workout, the Vikings opted to wait two additional days before that clock starts. According to a source, unless there is another injury, the Vikings likely will use all 21 days to decide.

Heinicke was expected to battle Shaun Hill as Teddy Bridgewater’s backup, but much has happened since training camp. Bridgewater was lost for the season to a knee injury and replaced by veteran Sam Bradford.

Bradford and Hill are on the 53-man roster, and Joel Stave is on the practice squad. So Heinicke will be a fourth quarterback at practice.

Heinicke was injured in July when he said his left foot accidentally went through a window while he and a friend tried to pry open a door after being locked out at an Atlanta residence. While initially disappointed and embarrassed, he said he was able to quickly shift his focus to getting back to full strength.

“You can’t sit back and dwell on it,” he said. “Right after it happened, I knew I was going to be out for a little bit, so I (concentrated on) on how I could get better. … Mentally, I wanted to get the playbook down and see if I can get better, and I think I did.”

Coach Mike Zimmer said Heinicke likely will practice Wednesday. He hasn’t done any work on the field with the team since June minicamp.

“I’ve never missed a practice or a game my entire life, so it was a shocker,’’ Heinicke said.
