The Vikings said the surgery was a success and Peterson was "resting comfortably."
Well, we now have the pictures to prove it.
On his Twitter account Sunday night, Peterson posted a series of pictures from his hospital bed.
The first post read:
My time bringing in the New Year was great! Thanks to family & a lil Blue Bell country ice cream
The second post read:
HAPPY NEW YEAR FANS & FAMIlY!!!
If a picture is worth a thousand words, I'd say Peterson is in good spirits.
Peterson underwent surgery six days after taking a hit to his knee in Week 16 against the Washington Redskins.
The injury is expected to require 8-9 months of recovery time.
