Ron Rivera said he will no longer allow his team to bring bats onto the field before games.
Rivera also denied that any Carolina Panthers directed homophobic slurs at Odell Beckham Jr. before Sunday's game.
Rivera announced his new policy regarding the baseball bats Tuesday, one day after photos and videos surfaced of star cornerback Josh Norman and practice squad player Marcus Ball carrying a black bat on the field during warm-ups.
"[The NFL] is the 'No Fun League' for a reason," Rivera said.
Giants players on the field reportedly heard Panthers defensive players directing anti-gay slurs and expletives at Beckham before the game.
