Hitoki Iwase just hit Norichika Aoki in the head.
Aoki is on the ground. He's talking, so that's a good sign.
They just put him on a stretcher and they're taking him off the field.
Iwase looks visibly shaken. At one point, it almost looked like he was about to cry.
Sounds like they are taking Aoki to one of the examination rooms in the stadium.

According to this Sanspo article, Aoki was taken to an area hospital for X-Rays and the results came back negative for any problems. That's good to hear.
I'm also a bit worried about Iwase. I'm not necessarily a fan of his, but he really looked like he was going to fall apart after he hit Aoki.

It was also mentioned here that Aoki is experiencing something similar to whiplash.
