There are plenty of games around the NFL that will be affected by weather on Sunday afternoon and one of those games is in Baltimore, Maryland where the Ravens are playing host to the Minnesota Vikings.

During pregame warm ups, there was snow coming down in bunches and all over the field, but that didn’t stop Ravens cornerback Asa Jackson from straying from his usual warm up routine.

While he was wearing a nice knit cap, Jackson was going with the shirtless look as he got used to the weather.

You wouldn’t advise your child to go out in the snow shirtless, but for a guy who is ready to play in the NFL and wants to get his body used to the weather it is acceptable — but that doesn’t mean he doesn’t have a few screws loose.

For those who are going to want to pinpoint Jackson when he is in full uniform, he will be sporting No. 25.
