Steelers rookie outside linebacker Jarvis Jones has been diagnosed with a concussion, the team acknowledged on Thursday.
Jones is the Steelers' first-round draft pick from the University of Georgia and is now regarded as a question mark for Sunday's game against the Ravens at Heinz Field.
Jones first told the Steelers' doctors Monday that he was dealing with concussion symptoms and hasn't been cleared to practice, according to the team.
The 6 foot 2, 245-pound starter was diagnosed with a concussion Wednesday and will be listed that way on the injury report today.
On Wednesday, the Steelers announced a head injury for Jones without mentioning specifically that he has a concussion.
Jones has 14 tackles, three quarterback pressures and four special-teams tackles through five games.
