Update, 8:17 pm:
David Wright has suffered a concussion, and will remained hospitalized overnight at the Hospital for Special Surgery.
David Wright was hit in the head by a pitch thrown by Matt Cain in the bottom of the fourth inning during today’s game.
Wright walked off the field under his own power, and Fernando Tatis replaced him as a pinch runner.
…it was a scary sight and I hope he is ok…he was down for about two minutes but it was a great sign to see him walk off the field under his own power…
