Sean McDermott didn't like the hit that knocked Josh Allen out of the game, and he sure didn't like the way the Buffalo Bills finished without their rookie quarterback.
The Oakland Raiders also lost their QB and a receiver in what's looking like a lost first season under Jon Gruden.
The Bills fell 20-13 in Houston on Sunday, with the Texans getting the go-ahead score when Johnathan Joseph intercepted Nathan Peterman's pass and returned it 28 yards for a touchdown with 1:23 remaining.
Allen threw for 84 yards and ran for 20 before he was hurt when Houston's Whitney Mercilus hit his right elbow with his helmet after Allen's pass. McDermott was angry about the hit and complained to officials that it was late.
"We talk about protecting the quarterback and I thought it was late," McDermott said. "But at the end of the day, the officials rule over the game, and obviously, they didn't."
Peterman threw two interceptions, the second one coming after Joseph's score.
"At the end of the game ... he was probably trying to do too much," McDermott said. "I don't want to paint it all bad, but we've got to protect the football and make sure we're smart."
Derek Carr and Amari Cooper both left the Raiders' 27-3 loss to Seattle in London with injuries. Carr was holding his left arm gingerly after getting sacked six times by the Seahawks and wouldn't have returned to the game had Oakland gotten the ball back, though he said afterward he was OK. The bigger concern was for Cooper, the two-time Pro Bowl receiver who was evaluated for a concussion after a helmet-to-helmet hit from safety Bradley McDougald. Gruden believed it should have drawn a penalty.
"I thought so," Gruden said. "I'm just hoping Amari is OK. I'm not going to say anything else. I hope he's all right. He's a great kid."
Wide receiver Seth Roberts also departed because of a concussion with 11 minutes remaining.
The Atlanta Falcons also lost multiple receivers, but were able to overcome their departures in a 34-29 victory over Tampa Bay.
Calvin Ridley, who was leading the Falcons with six touchdown catches, went out in the first half with an ankle injury and didn't return. Mohamed Sanu was sidelined in the second half with a hip problem after hauling in a 35-yard touchdown pass.
Also in that game, the Buccaneers lost defensive tackle Gerald McCoy, who walked slowly off the field in the fourth quarter with an undisclosed injury.
It appeared the Rams had lost receiver Cooper Kupp when he was carted off the field after wrenching his left knee when Broncos safety Darian Stewart horse-collared him on the Denver sideline in the second quarter. But he made a surprising return in the second half.
In other injury news:
—Ravens left guard Alex Lewis was taken to Vanderbilt University Medical Center with a neck injury after being hurt in the first minute of the fourth quarter of a victory at Tennessee. Lewis had been blocking on a run by Gus Edwards when he turned away from the pile slowly and went down. Trainers strapped him to a backboard and carted him off the field.
Coach John Harbaugh said there's a lot of optimism for Lewis, who was getting a CT scan at the hospital.
