For those who missed it like me, here's the argument between JD and Gibbons.

Looks like Donaldson almost clipped Gibby with his bat, and Gibby didn't like it. Seems like Gibby may have given Donaldson a little "Back off" shove. Water on the bridge I would assume.
Thole got in there and broke it up, his best contribution to the Jays this year.
