Bengals receiver Tee Higgins continues to make his way through concussion protocol and was a limited participant in Thursday's practice.

Cincinnati Bengals star wideout Tee Higgins returned to practice on Wednesday after being placed on Concussion Protocol.

Shemar Stewart (knee), Joseph Ossai (shin), and Shaka Heyward (fibula) all went full again. Stewart was cleared to practice Wednesday after missing the last four games on I.R., and Heyward remains on I.R. as well. Both could be activated this week with two open spots on the active roster.

During the matchup in Buffalo, Higgins hit his head hard on the turf twice. He was evaluated for a head injury in both instances but returned to the game. On Monday, Bengals coach Zac Taylor revealed that Higgins was back in the protocol after reporting symptoms Sunday night and Monday morning.

Defensive end Trey Hendrickson (hip/pelvis) did not participate in Wednesday’s session as he underwent season-ending core muscle surgery. Fellow defensive end, Shemar Stewart, looks like he’s ready to return from his knee injury as the rookie, who is on injured reserve, had a full practice.

The Cincinnati Bengals are hoping to get one important player back on the field this week while keeping another from exiting the lineup.

On Sunday, the Cincinnati Bengals faced the Buffalo Bills, and everyone saw the same terrifying sequence. Bengals wide receiver Tee Higgins twisted mid-air to make a spectacular catch, only to come down with the full force of his body driving his head into the frozen turf.

Cincinnati Bengals wideout Tee Higgins left the field twice on Sunday during the loss in Buffalo with obvious concussion concerns after hitting his helmet on the turf during catch attempts.

Tee Higgins was clearly unwell after suffering an obvious concussion. Shame on the Bengals and NFL for allowing him to keep playing.

From Tee Higgins' concussion issues to the defense's failure to cover tight ends, Cincinnati has a lot to sort through as season fizzles.
