The coldest condition Costa Rican Francisco Calvo had ever trained in was minus-11 degrees. Vadim Demidov, who grew up in Norway, once played in minus-18 degrees.
Oh, Celsius, though. By Fahrenheit standards, Calvo experienced about 12 degrees and Demidov was closer to 0 degrees. The Minnesota United FC center-backs aren't quite that hard-core. Yet, at least.
When United took to TCF Bank Stadium for the first time Friday, training ahead of the home opener Sunday, it was a brisk 7 degrees Fahrenheit. Goalkeeper John Alvbage actually showed off after practice how one of the team's practice vests had frozen and become crunchy.
That's pretty cold. When fellow expansion side Atlanta United FC visits at 4 p.m. Sunday, the projected forecast has the high temperature at a balmy 28 degrees, or 18 in feels-like terms, with winds at about 10 miles per hour and an 80 percent chance of snow.
Major League Soccer reported earlier this week this match could be one of the coldest in league history, with three previous matches played at below 30 degrees. It could also be the ninth match in league history with snow.
The New England Revolution rescheduled its home opener Saturday against Orlando City SC to September because of "extreme cold, with wind chills expected to take temperatures below 10 degrees," according to a club news release.
United coach Adrian Heath said he hadn't heard of any discussion to do the same for the Loons' first home match.
Heath isn't allowing any negativity or excuses about the weather from his players, adding that high winds would be the only factor that could really affect his strategy.
