Sobrato High receiver Jojo Nunn suffered a spinal fracture in his neck and a mild concussion during a playoff game against Valley Christian, his coach, Nick Borello, said Monday.

The junior was taken off the field Saturday night on a stretcher and transported to Regional Medical Center after being hit on a pass play in the Central Coast Section Division III semifinal at Live Oak High in Morgan Hill.

Nunn was not kept overnight.

He will be re-evaluated in six weeks and will wear a neck brace until then, Borello said, adding that the player will not need surgery.

Nunn, who was home Monday, said, "I'm not really relieved, but it could have been way worse than a break."

Asked about the play, which occurred in the closing minutes of Sobrato's 52-42 loss, Nunn said, "I knew the hit was going to come. I was just seeing what I could do to get the ball."

The injury came two days after San Jose lineman Isaiah Espinoza was taken to Valley Medical Center by ambulance after suffering a spinal contusion in the annual Big Bone Game on Thanksgiving Day against Lincoln.

Espinoza was released from the hospital Friday.

"It was scary," Espinoza told the Mercury News the day he was released. "I'm very thankful that I wasn't hurt worse."
