Hendrickson, 30, was the final remaining NFL holdout this training camp. It’s not yet clear if he will practice as he looks to get his new contract. The news comes less than a week after rookie defensive lineman Shemar Stewart ended his own lengthy standoff with the Bengals.

As Hendrickson looked for a new deal earlier this offseason, the Bengals initially permitted him to seek a trade to a team that would give him the contract he wanted. Less than a month later, however, Cincinnati walked back that offer and reportedly wasn't interested in trading him.
