BUFFALO, N.Y. -- Jacksonville Jaguars quarterback Blake Bortles criticized the officiating following his team's 28-21 loss to the Buffalo Bills at New Era Stadium on Sunday.

Bortles was upset that there was not a pass interference penalty called on a third-down pass to Allen Robinson on the Jaguars' final drive.

"The one on A-Rob was brutal," Bortles said. "I don't know how that wasn't called. Yeah, that was bad.

"Do you get fined for saying that?"

When he was told that he most likely would get fined, Bortles paused for a second and considered what he had already said.

"Might as well just keep talking then," he said. "Yeah, that was horrible. Jesus, I don't know how that ... OK, I'm done."

The play in question was a back-shoulder throw to Robinson on third-and-4 from the Buffalo 40-yard line. The defensive back appeared to get a hand on Robinson to prevent him from turning his body to make the catch, and the ball was incomplete.

"It's unacceptable," wide receiver Allen Hurns said. "The third-to-last play, where A-Rob, where the ball was low, that was pass interference. What sucks is we're going to send it in and they'll come back to say, 'Yeah, we should've made this call,' but it's too late for that. It's just unacceptable, man."

The Jaguars were penalized for delay of game on fourth down, and Bortles completed a 4-yard pass to Marqise Lee, turning the ball over on downs with 3 minutes, 25 seconds to play. Jacksonville never got the ball back.

Earlier in that drive, Bortles nearly completed a deep pass down the sideline to tight end Neal Sterling, but Bills cornerback Nickell Robey-Coleman banged into Sterling for what appeared to be pass interference. However, the officials didn't throw a flag.

Robey-Coleman was called for a controversial pass interference penalty in last year's Jaguars-Bills game in London. That penalty kept the Jaguars' game-winning drive alive.
