From now on, the only weapons allowed in Major League Baseball clubhouses will be wooden bats.
Players entering their teams' spring training camps will be greeted by signs reminding them that "firearms, explosives, daggers, metal knuckles, switchblade knives and knives having blades exceeding five inches" are strictly prohibited from clubhouses going forward, SI.com reports.
The rule was developed by the league and agreed to by the players' union last year, following the Plaxico Burress incident, when the New York Giants wide receiver accidentally shot himself in the thigh. The league decided to post signs implementing the policy after Washington Wizards' guard Gilbert Arenas brought a firearm into his team's locker room earlier this season.
Officially known as "Major League Baseball's Weapons-Free Workplace Policy," the ban applies to all spring training, practice and playing field facilities. Security and law enforcement officials are excluded, and MLB also reserves the right to grant other exceptions if necessary.
