The redshirt junior is expected to be fine, but Ohio State has yet to confirm or comment on his status. The hospital trip caused a social media stir a few hours after the top-ranked Buckeyes wrapped up practice ahead of Monday's season opener at Virginia Tech.
According to the Toledo Blade, Jones remained in an emergency room late Wednesday as a precautionary measure, but his mother, Florence, told the newspaper, "He is good" and that it was "just a headache."
Jones has been competing with J.T. Barrett for Ohio State's first-team quarterback job during training camp after he led a remarkable three-game run through the postseason en route to the national championship in the first starts of his career.
Praised for his toughness and arm strength, Jones is expected to contribute whether or not he wins the job outright, with coach Urban Meyer indicating the Buckeyes could use both quarterbacks when they open the season against the Hokies.
Said Meyer on Wednesday without revealing his choice: "I have an idea who's gonna take the first snap. The favorite? I'm not sure I like that word, but I have a feeling on who's gonna take the first snap. I still think that after today."
