James Van Der Beek is slipping back into his old jersey amid his health battle! The 48-year-old actor - who is battling stage three colorectal cancer - took to Instagram on Monday to post a video of himself rocking a blue and white jersey, featuring the name Moxon on the back. Fans know the shirt is a reference to his character Jonathan "Mox" Moxon from the 1999 film Varsity Blues. And he put it on again for a good cause.
