Brandon Belt took a curve ball to the head, suffering his fourth concussion.

“It’s a curveball that caught him flush,” Giants manager Bruce Bochy said. “He’s been through this before, so it’s obvious there are some concerns there. Our hope is this thing’s going to be a lot better tomorrow.”

This would be Belt’s fourth concussion in eight years.

I hope he recovers. Multiple concussions can lead to permanent damage.
