The Bengals were unsure whether or not linebacker Vontaze Burfict would be able to play in Week Two after suffering a concussion against the Ravens in the season opener.

Burfict was able to get clearance through the league’s concussion protocol and took the field against the Falcons, only to see his day come to an early end with what the team called a stinger at the time. Burfict missed practice on Wednesday, but he wasn’t listed as having a stinger.

Burfict is listed as suffering from another concussion. Geoff Hobson of the team’s website reports that Burfict began having concussion symptoms after being diagnosed with the stinger and he’ll now reenter the protocol before he can be cleared to practice or play in a game. After a second concussion in such a short amount of time, Burfict may need to wait a bit longer before the green light comes this time.

Wide receiver A.J. Green, who hurt his foot in the Falcons game, also didn’t practice, but said he’ll try to give it a go on Thursday. Guard Kevin Zeitler was in a boot after injuring his calf and Hobson believes he’s doubtful to be on the field against the Titans this week.
