I think he whacked it on Thursday morning while I had Sydney over at the neighbor's place grazing. These photos would be 24 hours post whack.
I checked him again this afternoon and the filling was still there, but after a ten minute turnout, the filling was gone. He ran around like a lunatic for the better part of an hour and his leg was clean and tight when I put him away (after a thorough hose down).
I don't ride until 4:30 on Sunday so I am hoping that gives him time to heal up. I am not worried about the abrasion, it's minor. What concerns me is the filling. As long as it is mostly gone by Sunday, we'll go. If not, we stay home.
