Here today, gone tomorrow.

No, really.

And Brad Sorensen gets it. The quarterback had been out of football for four months before the Vikings, down two quarterbacks at practice, needed another arm. He was let go earlier this week once Teddy Bridgewater and Shaun Hill got some rest. And suddenly, this stay at home was over.

"About 24 hours," Sorensen said. "And was on a flight right back."

Driving home from Costco with his daughter, Sorensen received word of Bridgewater's dislocated knee and torn anterior cruciate ligament suffered on a routine drop back at the start of Tuesday's practice.

"My brother called me and said, 'hey, did you hear what happened?'" Sorensen said. "I thought he was joking. You would never expect a freak accident like that. Sure enough, unfortunately, that happened. My agent called me and said there's a good chance."

The Vikings' search for a quarterback immediately landed Sorensen again, as a stopgap to carry them through the preseason if needed. He re-signed on Wednesday and caught a 6 a.m. flight out of Salt Lake City, just missing the team's morning walkthrough.

He wasn't even supposed to play in Thursday night's preseason finale. The plan was to give Joel Stave, the undrafted rookie out of Wisconsin, a full look before the Vikings must decide on his future with the team.

"I've been in the building less than a week," Sorensen said. "I haven't taken many snaps. And for them to put — you don't want to go out there and make everybody look dumb, that's the biggest thing. So I think they were kind of hesitant. So the plan was hey, we'll play you if we can, but Joel is going to get the time."

Five minutes before halftime, Stave took his seventh hit of the game and shortly after was pulled. He was put through the concussion protocol and Sorensen, a 2013 seventh-round pick by the Chargers, was forced into action as the Vikings rested starter Shaun Hill.

Sorensen's unpredictable stint with the Vikings will likely end with his four preseason completions for 59 yards and a touchdown. After halftime, the offense leaned heavily on two rookie running backs in Jhurell Pressley and C.J. Ham.

"I prepared," Sorensen said. "And they kind of simplified things for what I was able to do in the second half."

Now as the Vikings search league-wide for another quarterback, Sorensen will be part of the annual wave of fringe NFL players fearing, or simply expecting, a phone call Saturday afternoon when all rosters must be trimmed to 53 players.

"I figured if [Sorensen] came in for three days," head coach Mike Zimmer said after Thursday's exhibition. "He should play."
