Diontae Johnson expressed frustration with the officiating crew following the Pittsburgh Steelers' loss to the Jacksonville Jaguars on Sunday afternoon.

The wide receiver was especially upset about an offside call on right guard Isaac Seumalo that negated a 55-yard Chris Boswell field goal. Boswell's ensuing attempt after the penalty sailed wide right.

If the field goal stood, it would've cut the Jaguars' lead to three going into the half.

"Refs were just killing us the whole game," Johnson said. "The same refs we had at training camp. I didn't like the refs today. At the end of the day, we can't keep complaining about the refs. Like Coach [Mike Tomlin] say, we can't worry about the refs, whatever. But everybody's different.

"I didn't like the refs today. They must've got paid good today or something, but they blew -- that field goal, that hurt us coming into the half. We needed that."

Johnson also expressed frustration with the inconsistency of roughing the passer calls, including a non-call when Kenny Pickett was knocked to the ground by defensive end Adam Gotsis with 17 seconds remaining in the first half.

"They was calling some stupid stuff," Johnson said. "They should get fined for calling bad, making worse, terrible calls and stuff like that. That's how pissed I am. They cost us the game. I don't care what nobody say. They cost us the game."

Trevor Lawrence says that his left knee has improved rapidly over the past two days and that he's optimistic he'll be able to play for the Jacksonville Jaguars in Thursday night's game at the New Orleans Saints.

"I'm going to do everything I can to be out there," Lawrence said. "I feel a lot better today than I would've thought. So I like how I'm progressing, and I'm going to do everything I can to be out there on Thursday.

"It's progressed really well through the past 24, 48 hours. So, really like where it's at."

In his third season, Lawrence hasn't missed a game as a professional.

Lawrence was hurt on a third-and-7 play from the Indianapolis 16-yard line with 3:10 remaining in the Jaguars' 37-20 victory at EverBank Stadium on Sunday. 

Trevor Lawrence said he will undergo further testing on his left knee Sunday night, but the Jaguars quarterback said his knee is bruised and he's feeling OK.

However, he stopped short of saying he would be able to play in Thursday night's game at the Saints.

Buffalo Bills pass-rusher Von Miller has been activated off the physically unable to perform list and is back on the team's 53-man roster. The move puts Miller in position to likely make his return in Sunday's game vs. the Jacksonville Jaguars in London (9:30 a.m. ET, NFL Network).

Cornerback Tre'Davious White, who suffered a season-ending torn right Achilles in last week's win vs. the Dolphins, was placed on injured reserve in a corresponding move.
