Browns kicker Phil Dawson skipped the team's voluntary workout on Monday in a believed contract protest.
Dawson, the second-leading scorer in team history, is in the final year of his deal.
Cleveland general manager Tom Heckert would not say if Dawson's absence Monday was because of a contract dispute.
"I really don't want to get into it, but that's not the whole thing with him," Heckert said.
