"I know he's still here, I know he's fighting," he told the network. "We appreciate all the prayers and support we have been getting from people all over, not just the country, but the world. It really means a difference for my family to see that, and I know it'll mean a difference to Damar when he sees that."
Damar's team members were horrified by the moment
He gave a glimmer of light when he said that Damar is "improving from where he was yesterday," but it's clear he's not out of the woods yet.
Dorrian said he was watching the game with Damir and family. "First we thought it was just a normal hit, and we thought that he popped back up maybe take a couple plays off and get back," he said when Damar went down following a hit from the opposition. "But the way my nephew [Damar's younger brother] I have never heard him scream and cry like that. And then, when it was 10 minutes gone past, and then 20 minutes gone past, I knew something was serious."
He added: "Once they canceled the game, we loaded up two carloads and we drove from Pittsburgh to Cincinnati, to just be here to support my nephew."
