Right after he walked off the field and began speaking with a coach (? not sure who as his back was to the camera), I thought I immediately saw him say 'I'm sorry. I'm sorry'. At least that's what I concluded from my limited lip reading skills.
Yeah he's got to know that too. With all the choreography they practice on TD's...I'm sure it has been made clear that the goal post is still off limits. I can't imagine Zimmer not making that clear. I do believe him though that it wont happen again.
On the positive though....Diggs looks like he is fully healthy from the groin injury. That is huge for our offense going forward.
