A bicyclist who had to undergo life-saving surgery after being hit by a vehicle made it through the procedure – and he's in critical condition, but with "an opportunity to keep living and fighting."

Bryan Joas, 45, from Eagan, was traveling along Highview Ave. in Eureka Township at 5:45 p.m. Tuesday when he was struck by a vehicle heading east on 250th Street West.

Joas underwent a life-saving surgery Friday morning, according to a posting on his CaringBridge page, with his family saying they "need a miracle."

An update later that day titled "We got our miracle" says the doctor was able to go forward with the procedure, and Joas made it through. He's in critical condition, but the surgeon is "guardedly" optimistic, the post says.

"[Joas' wife] Shauna had the courage to give the surgeon the chance to allow Bryan an opportunity to keep living and fighting, and all of you praying and sending your love gave Bryan the strength to keep fighting!" the update reads.

Authorities looking for driver

The Dakota County Sheriff's Office has issued an appeal for information from anyone who may have seen a vehicle in the area at the time. They're offering a $1,000 reward for details leading to the identification of the driver and vehicle. (Note: They initially asked about a white pickup, but the sheriff's office has since said it was only in the area at the time and shouldn't be considered the primary suspect vehicle.)

Those with information should call Sergeant Dawanna Witt at 651-438-4736 or Detective Ryan Fitzgerald at 651-438-4729.

Joas' wife Shauna posted about the incident earlier this week, saying Bryan went out biking after work on Tuesday to enjoy the weather, but she grew worried when he hadn't returned by 7 p.m.

Police arrived at their home telling her he had been in a serious accident and had been taken to North Memorial Hospital in Robbinsdale, with injuries including a broken pelvis, lower back and ribs.

Since arriving in the hospital he has had his large intestine removed and is on dialysis for kidney failure.

Dakota County Sheriff Tim Leslie told the Star Tribune that Joas works in Burnsville, and on occasion would take a circuitous cycling route home that sometimes ran between 50-75 miles.
