Rob Gronkowski will indeed sit out Monday's game in Miami.

The NFL announced that appeals officer Derrick Brooks denied Gronkowski's appeal of the one-game suspension he was issued for throwing a forearm to the back of Tre’Davious White’s head during Sunday’s victory over the Buffalo Bills.

Even before the appeal decision came down, the Patriots knew they had to prepare to play the Dolphins without him.

"It's not our decision," Bill Belichick said earlier in the day.

Gronkowski is an important part of the offense, both as a pass catcher and blocker. He has 55 catches for 849 yards with seven touchdowns. To that end, offensive coordinator Josh McDaniels spoke about the season Gronk has had to this point.
