INDIANAPOLIS (AP) -- Philadelphia Eagles coach Nick Sirianni pushed back against the Green Bay Packers' proposal to ban the tush push.

"I've seen some of the stuff that it's an automatic play," Sirianni said Tuesday at the NFL's scouting combine. "I almost feel a little insulted because we work so hard at that play. The amount of things that we've looked into, how to coach that play, the fundamentals. ... I can't tell you how many times we practice the snap. We practice the play because it's not a play that was easy to practice in different ways. We figured out how to practice it.
