Rathbun was about to shuffle through his notes when he leaned back and began what appeared to be some sort of seizure.
Bally Sports Southeast, which airs the Hawks games, said later on Twitter that Rathbun was “treated for dehydration” and was “stable and responsive” as he headed to the hospital for “further evaluation.”
The station reported more favorable news about Rathbun on Tuesday, writing that “all tests were very favorable” and that Rathbun would likely be released from the hospital later Tuesday.
“He will return to the broadcast booth only after he is well rested and fully recovered,” the Bally Sports statement read.
The Hawks lost to Oklahoma City, 121-114.
