N.F.L. Week 1 Live Updates: Nick Foles Knocked Out of Game

The N.F.L. began its 100th season with a defensive slugfest between the Green Bay Packers and the Chicago Bears on Thursday night that reminded people a bit too much of what football looked like 100 years ago. There should be quite a bit more offense on Sunday. Come back here all day for highlights, injuries, top performances and (presumably) even more drama from Antonio Brown.

Nick Foles Injured in Jacksonville

In what could prove to be a terrible blow to the Jacksonville Jaguars, Nick Foles, the team’s new starting quarterback, was forced out of the game with an injury to his non-throwing shoulder while throwing his first touchdown pass of the season. He will not return.

The game looked like it could turn into a blowout with Foles out and Patrick Mahomes cruising, but Gardner Minshew, a rookie out of Washington State, has been holding down the fort just fine in Foles’s absence. As a result, Jacksonville trails the Kansas City Chiefs by 23-13 at halftime.

It was midway through the first quarter, with Jacksonville down by 10-0, when Foles launched a deep ball into the end zone that D.J. Chark pulled down for a 35-yard touchdown. Shortly after Foles released the ball, he was crushed into the turf by Kansas City’s Chris Jones.

Foles immediately left the field, and reports from the sideline indicated that he had not gone to the locker room, but had instead gone straight for X-rays on his left arm and shoulder. The team announced almost immediately that he would not return though they did not specify the extent of the injury.

He returned to the sideline in street clothes late in the second quarter.

Foles has had an up-and-down career, but after his shocking win over the New England Patriots in Super Bowl LII and his strong play toward the end of last season, he was expected to help stabilize a Jacksonville offense that had struggled to live up to the team’s defense.

With Foles out, and the team having already fallen behind by 17-7, the Jaguars’s offense was put in the hands of Minshew, a sixth-round draft pick who threw for a whopping 4,779 yards last year while running the Air Raid offense under Coach Mike Leach at Washington State.

The Air Raid is similar enough to the style Nick Foles played in Philadelphia, and that Jaguars offensive coordinator John DeFilippo has installed, that Jacksonville appeared to be in good hands. Sure enough, Minshew completed the first nine passes of his N.F.L. career — the first quarterback to do that since Brad Johnson in 1994 — for 128 yards. That helped lead the Jaguars to a pair of field goals.

Kansas City’s offense, meanwhile, will be limited going forward as a result of a shoulder injury to Tyreek Hill that will keep the superstar receiver out for the remainder of the game. On Friday, Hill signed a three-year contract extension with a reported $35 million in guaranteed money. In addition, Patrick Mahomes, who has thrown for 313 yards and two touchdowns in the first half, briefly limped off the field with an ankle injury. Mahomes returned to the field quickly, but has been walking awkwardly between plays.

Lamar Jackson Is Thriving

Remember when there was concern over whether Lamar Jackson could succeed as a quarterback once teams adjusted to Baltimore’s run-heavy approach? He started Sunday’s game by completing 10 of 11 passes in the first half for 210 yards and four touchdowns, including an 83-yarder to Marquise Brown. He has the Ravens leading the hapless Miami Dolphins, 42-10.

It would not be wise to draw too many conclusions in a game being played against the Dolphins, but with Baltimore putting up 390 yards of offense in the first half — including 181 on the ground thanks in part to the free agent addition of Mark Ingram — it certainly looks like a good idea for the Ravens to have stuck with the quarterback that got them into the playoffs last year.

The Dolphins rallied to score a touchdown on a Ryan Fitzpatrick pass in the final minute of the second quarter, but that barely put a dent in Baltimore’s lead.

Thursday’s lone touchdown came nearly two minutes into the second quarter of the snoozefest of a game between Green Bay and Chicago. The wait was not nearly as long on Sunday. On the third play of the game between Kansas City and Jacksonville, Patrick Mahomes and Sammy Watkins of the Kansas City Chiefs connected on a 68-yard catch-and-run touchdown.

The Chiefs’ reworked defense forced a three-and-out, and while things did not go quite as well on Kansas City’s second offensive possession, a 42-yard connection between Mahomes and Travis Kelce was the key to getting Harrison Butker in range for a 28-yard field goal. The Chiefs lead by 10-0.

Mahomes threw a remarkable 50 touchdowns last season in his M.V.P. season and it is looking like he has no plans to slow down this year.

Today’s Key Inactive Players

The two most notable inactives in the 1 p.m. games are Adrian Peterson, a running back for the Washington Redskins and Marcell Dareus, a defensive tackle for the Jacksonville Jaguars.

Peterson, who at 33 had a comeback season for Washington last year, is a healthy scratch as Coach Jay Gruden decided the rookie Darrius Guice was his better option at running back and Wendell Smallwood was seen as a better option on special teams.

Dareus, a key to Jacksonville’s run defense, is still working his way back from an elbow injury. His absence could be terrific news for Damien Williams and LeSean McCoy, as the Kansas City Chiefs should have significantly more room to run.

What to Look For in Week 1

• The Los Angeles Rams are seeking to avoid the Super Bowl hangover that has plagued so many N.F.L. teams in recent years. Fresh off signing quarterback Jared Goff to a contract that guarantees him $110 million, they open on the road against Cam Newton and the Carolina Panthers. (1 p.m., Fox)

• How does Patrick Mahomes follow up winning the N.F.L.’s Most Valuable Player Award in his first season as the starting quarterback of the Kansas City Chiefs? Can Nick Foles, reunited with the offensive coordinator John DeFilippo, give the Jacksonville Jaguars the offense they’ve lacked in recent years? We’ll get a glimpse of both when the Chiefs take on the Jaguars in Jacksonville, Fla. (1 p.m., CBS)
