FOXBOROUGH, Mass.

His arms finally free, Rob Gronkowski clapped when he saw the yellow flag in the endzone. The Patriots would have one more chance to win.

Seconds later, that chance was lost.

One day later, Bill Belichick wouldn’t discuss the officials’ decision to wave off a penalty on the final play when Carolina linebacker Luke Kuechly wrapped his arms around Gronkowski as Tom Brady’s pass sailed toward them.

There was nothing New England’s coach could do about the 24-20 loss to the Panthers on Monday night. Better to focus on his second straight prime-time challenge coming up Sunday night against the Denver Broncos.

“I don’t really have any comment to add about the officiating or any of those calls,” Belichick said during a conference call Tuesday. “If you have any questions on that, you can talk to the league office and the officiating department. Let them give their explanation.”

Or you can listen to Patriots defensive end Rob Ninkovich.

“Both arms are being wrapped around the receiver as the ball’s in the air,” he said on WEEI radio. “A foul’s a foul. No matter what it is, the ball’s there. It’s not like the ball’s 20 feet over his head or it lands on the 5- yard line or something.”

With the ball at the Carolina 18 and a lineman bearing down on him, Brady didn’t step into the throw as he usually does. The underthrown pass was intercepted by Robert Lester about 4 yards into the end zone. Gronkowski, a few yards behind Lester, couldn’t move toward the ball with Kuechly bear-hugging him.

Referee Clete Blakeman conferred for a few seconds with back judge Terrence Miles, who threw the flag. Miles shook his head. Then Blakeman said there was no foul and the game was over. Later, Blakeman told two pool reporters that Miles had called defensive pass interference, but the ball was uncatchable.

“I don’t make the calls or the rules,” Brady said. “I wish it wouldn’t have come down to that. I think there were plenty of plays we could’ve made.”

The Patriots (7-3) will have to make a lot more of them against the Broncos (9-1), the NFL’s highest-scoring team, and Peyton Manning, who leads the league with 34 touchdown passes in 10 games.
