It's supposed to be 49⁰ on Friday, but also a high of 14⁰ Sunday.. so while Friday Afternoon Football would be ideal in terms of weather, it could be significantly worse.
Coveralls, a good pair of boots, gloves, hat... no biggie, especially without snow. Hell, these days you can get in with battery operated heated socks and gloves (not so sure about the full heated jackets, but guessing no if they have a huge battery pack).
