Watch: Bills DE Shaq Lawson appears to shove fan

Week 12's overtime thriller between the Buffalo Bills and Philadelphia Eagles was an instant classic.

After going down 34-31 in overtime, Eagles quarterback Jalen Hurts — already responsible for three passing touchdowns and a rushing TD — scored on a 12-yard run to give Philadelphia a 37-34 walk-off win.

With the loss, Buffalo fell to 6-6. Dropping four of their past six games obviously has the Bills frustrated, but defensive end Shaq Lawson took the loss particularly hard.

Lawson, along with fellow defenders Ed Oliver, Jordan Phillips and Greg Rousseau, jawed with a green-clad fan sitting behind the Buffalo sideline. Lawson appeared to shove the fan during the interaction.

Security at Lincoln Financial Field appeared to stand by and let this altercation play out a few seconds too long, long enough for Lawson to interact with the fan. This should have been nipped in the bud well before Lawson had easy access to the fan.

Lawson could face discipline by the NFL. Whether that's a fine or suspension remains to be seen, but this is an ugly look for Buffalo following another ugly loss.
