EL DORADO (CBS13) – Union Mine High School is quiet but online, offering a strong outpouring of support for two players who were hospitalized Friday night.

“Please everybody pray for my little brother, he’s getting emergency brain trauma surgery… We need your prayers please,” tweeted Nate Brown about his brother Nick.

“It was evident that they weren’t feeling well. They were going in and out of consciousness. And so based on that, we were able to get those young people to the hospital,” Wehr said in a phone interview.

Wehr says Nick and fellow Union Mine player Justin Schwartz were rushed to the emergency room. Sunday, Brown’s family revealed that Nick “suffered a high impact blow to the head that caused a subdural brain bleed.”

Doctors are continuing to closely monitor Nick following an emergency craniotomy.

“We videotape these games, so we will be doing some work on our own to look at those and talking to the kids to the coaches,” Wehr said. “We have a lot of work ahead of us and are actually in the midst of that right now.”

Shortly after Nick was admitted, his brother tweeted again: “Nick had a successful surgery tonight. He is asleep and will be for about a week. Thank you everyone for your prayers, the lord is on our side.”

Nate has also set up a tribute page for his little brother. In his latest update Saturday evening, he wrote “Nick is in good condition, he is still unconscious but he is moving everything around very well. He is in stable condition as far as we know.”

Hospital officials say Nick remains in critical condition.
