The 32 NFL teams are busy preparing for the new season. But in some training camps, not all players are on the field.

The NFL is in the starting blocks, and training camps are underway. But not all coaches have their full squads at their disposal.

That’s because some players are pushing for new contracts—and they’re taking different approaches.

Veterans Trey Hendrickson (Cincinnati Bengals) and Terry McLaurin (Washington Commanders) are currently not on the training field; they want to use their absence (holdout) to push through new contracts. Both stars are entering the final year of their contracts and are demanding new deals.

Meanwhile, Quinshon Judkins, the Cleveland Browns’ second-round pick, is the only rookie not yet under contract. However, this is likely due to the running back being accused of domestic violence. Judkins is currently not participating in training.

James Cook wants to become a top earner

Pass rusher Micah Parsons of the Dallas Cowboys is currently watching the action from the sidelines, as is offensive lineman Elgton Jenkins of the Green Bay Packers. Both players are officially “injured,” but are likely sitting out training primarily due to ongoing contract negotiations. This approach is known as a “hold-in.”

The situation is different for James Cook of the Buffalo Bills. The running back is participating in training camp as normal, and a holdout is not currently an issue. However, his stance on demanding a top contract has not changed.

“We are in talks,” he said, making it clear: “I deserve what I’m asking for and what I need. And it will happen eventually.”

Holdouts can quickly become an expensive affair for players. For every day they miss, they have to pay a fine of just under $50,000.

Last season, for example, Brandon Aiyuk, wide receiver for the San Francisco 49ers, signed a four-year deal that could earn him up to $120 million. He had previously refused to participate in training while in a “holdout.”
