Physical toll on Andrew Luck through 6 NFL seasons:
» Torn cartilage in 2 ribs
» partially torn abdomen
» a lacerated kidney that left him peeing blood
» at least 1 concussion
» a torn labrum in his throwing shoulder
» and this mysterious calf/ankle issue that led to this

From 18 to 12. To two of the best QBs I’ve ever had the pleasure of physically seeing in a #Colts uni tossing the rock, I only have two words for you:

Thank you.

Signed,
A REAL Colts Fan
