49ers Make Uniform Change for Cardinals Game Ahead of Possible Record Temperatures

The San Francisco 49ers will wear alternate throwback uniforms that feature white pants to prepare for projected record-breaking temperatures during the team's Week 5 matchup with the Arizona Cardinals at Levi's Stadium.

Temperatures are expected to be about 95 degrees at kickoff on Sunday and will rise towards 100 degrees throughout the afternoon, per The Athletic. The game is projected to be the hottest in the history of Levi's Stadium, surpassing the previous high of 90 degrees during a preseason contest in Aug. 2017.

49ers head coach Kyle Shanahan said that the team attempted to switch to all-white uniforms in order to combat the heat, but the request was denied by the league.

"We asked on Monday, and we weren't allowed to do it," Shanahan said, via David Bonilla of 49ers Webzone. "You had to [request] it before the season started. So in order for us to do it, we've kind of got to make like a conscious decision or a commitment before the year that we wear all whites until like the middle of October or whatever, and then go to normal."

The Cardinals will be wearing all-white uniforms during the game, according to The Athletic.

Shanahan told reporters that many players on the team already take IVs as part of their weekly routine, but he expects that number to increase on Sunday (via ESPN's Nick Wagoner).

The 49ers currently sit in second place among NFC West teams with a record of 2-2, while the Cardinals are at No. 3 with a 1-3 record. In addition to facing off against each other, both teams will need to battle the high temperature.

Kickoff on Sunday is at 4:05 p.m. ET.
