The Dallas Cowboys and San Francisco 49ers are not set to face off until Week 5, but their first clash has already taken place on social media.
Niners receiver Jauan Jennings commented, "Can't wait to see him again," on a video of him knocking Cowboys cornerback Trevon Diggs to the ground.
Diggs answered by saying Jennings would "never line up in front of me in your life."
