Amid what constitutes scalding conditions for Northern California, 49ers coach Kyle Shanahan told reporters Friday that the team asked the NFL to switch to white uniforms from red uniforms and was refused. The team will be able to wear white pants with its throwback uniforms, but that's it.

With record heat descending on the Bay Area on Sunday, the NFL has denied the San Francisco 49ers' request to wear white uniforms for their home match against the Arizona Cardinals. The decision will leave the 49ers in their red home uniforms for the game in Santa Clara, where temperatures are expected to hit 100 degrees.

The league rejected the Niners and they will have to wear the darker uniforms despite the heat wave. Head coach Kyle Shanahan explained to reporters how the home team made the inquiry as well as the rationale behind the league's response.
