Ding, ding.

In what may be the least surprising development of any joint practice in NFL history, squabbles and skirmishes were abound between the Carolina Panthers and New York Jets on Thursday morning.

The first fit of fisticuffs went down when Panthers wideout Terrace Marshall Jr. bested Jets cornerback D.J. Reed on a fade ball from quarterback Bryce Young. After the fourth-year receiver reeled in the pass for an impressive touchdown, he flipped the ball at Reed.

Reed, of course, didn't take too kindly to the gesture. Things got heated, the teams convened and Reed proceeded to even fling the ball at Panthers running back Chuba Hubbard.

Then, a second scuffle would break out—this time, between Panthers running back Mike Boone and Jets defensive lineman Michael Clemons. Per Mike Kaye of The Charlotte Observer, Clemons took a swing on Boone and Boone would reciprocate with an attempt of his own . . .

And if two fights weren't enough, then how about a third . . . ?

Welcome to the dog dawg days of summer!
