Sean McDermott didn’t like the hit that knocked Josh Allen out of the game Womens Derek Carr Jersey , 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.For the Titans, linebacker Derrick Morgan hurt a shoulder and did not return, and left guard Quinton Spain departed with an injured right shoulder.—Vikings cornerback Mike Hughes limped off in the fourth quarter of Minnesota’s victory over Arizona with an apparent left knee injury.—Browns receiver Rod Streater suffered a neck “stinger” while covering a punt in the first quarter and did not return to a loss to the Chargers. His injury complicated Cleveland’s issues at wide receiver as Rashard Higgins and Derrick Willies were also out with injuries. Linebackers Joe Schobert and James Burgess went out with hamstring injuries in the second half.—Jets receiver Quincy Enunwa injured an ankle on a fumble in the second quarter of a victory over Indianapolis and didn’t return. Safety Marcus Maye left with a hand injury in the third quarter. The Colts, who were already playing without several injured starters, lost receivers Robert Turbin (right shoulder) Antonio Brown Raiders Jersey , Ryan Grant (ankle) and Marcus Johnson (right ankle).—Cowboys receiver Tavon Austin was forced out in the second half of a rout of Jacksonville with a groin injury, while the Jaguars lost defensive end Calais Campbell (rib) and tight end Niles Paul (knee). The 49ers will see Khalil Mack up close on Sunday when they take on the Bears, but they thought four months ago that they were in a position to put Mack in a 49ers uniform — and the Raiders probably wish that was the trade they had made.As 49ers General Manager John Lynch explained last month, he tried hard to acquire Mack in a trade with the Raiders. Lynch actually said the offer he made was better than the offer the Bears made, but the Raiders went with the Bears’ offer. Lynch wondered if the Raiders didn’t want to trade Mack to the Bay Area’s other NFL team.That might have been a consideration, but a bigger issue was probably that the Raiders didn’t really see the 49ers’ offer as better than the Bears’ offer. Lynch didn’t say exactly what the 49ers offered for Mack, but assuming it was approximately the same package of draft picks that the Bears ended up giving the Raiders, it’s possible that the Raiders turned the 49ers down simply because the Raiders expected the Bears to be picking higher in the draft order.And, at the time, that would have been a reasonable assumption. In August, before the Mack trade, the Las Vegas odds pegged the Bears as a 6-10 or 7-9 team this season, and the 49ers as an 8-8 or 9-7 team this season. It was reasonable for the Raiders to think that if both the Bears and the 49ers were offering their first-round draft picks, the Bears’ offer was better.That turned out to be very wrong: The 49ers are 4-10 and still in contention for the first overall pick in the draft, while the Bears are 10-4 and will send the Raiders a pick no higher than No. 21, and probably more likely in the high 20s or even the 30s. Of course, we can never say for sure what would have happened if the Raiders had traded Mack to the 49ers (the 49ers may have won more games, and the Bears may have won fewer games), but it’s unlikely that Mack would have made such a big difference as to turn the 49ers into a playoff team and the Bears into a team vying for the first overall pick.So when Mack lines up against the 49ers on Sunday, Lynch won’t be the only one wondering what might have been. Jon Gruden may also see that game and wonder if his team would be in better shape going forward if he’d traded Mack to San Francisco instead of Chicago.
