Mularkey said the team sent all of its proposals to the league

Mularkey said the team sent all of its proposals to the league for approval, adding that the NFL signed off on the one involving injury talk.

"Yes, absolutely," he said. "Everything that we believe we would like to address, we send that to the league, and the league approves everything."

Mularkey said the NFL mandates that teams go over the league's rules and procedures handbook before camp. He said the team has the option of adding its own rules to the NFL's list, and that's where the injury crackdown arose.
