The highly anticipated debut for starting quarterback Kyler Murray was cut short on Sunday at U.S. Bank Stadium. He left the game between the Vikings against the Green Bay Packers midway through the first quarter after taking a late hit to the head and was evaluated for a concussion before officially being ruled out.

“I don’t have a lot to update,” head coach Kevin O’Connell said after the game. “I did just see him and he seemed to be doing pretty well.”

The scene was scary to witness.

After scrambling outside of the pocket, Murray slid in an attempt to avoid contact. He initially got hit by edge rusher Lukas Van Ness before safety Javon Bullard flew in late and delivered a shot to the head.

“It almost puts me in a bad head space in a way,” running back Aaron Jones said. “You never want to see anybody get hit like that,”

The reaction from Murray didn’t look good as he stayed down on the field while trainers quickly tended to him. The good news? He walked off under his own power before immediately being taken to the locker room.

“I was very, very happy to see him walk off the field,” star receiver Justin Jefferson said. “I saw him in the locker room having a smile on his face. He was congratulating the guys. Hopefully we get him back sooner than later.”

Though it’s still unclear how long Murray will be out, if he indeed suffered a concussion, it’s highly unlikely that he will be available to play next week when the Vikings travel to play the Chicago Bears.

In his absence, backup quarterback Carson Wentz stepped in and performed admirably, completing 12 of 19 passes for 133 yards and a trio of touchdowns. He now appears to be in position to start for the Vikings against the Bears.

Cardinals upset chargers

Murray’s successor with the Arizona Cardinals, Jacoby Brissett, threw for 277 yards and a touchdown in an upset victory against the Los Angeles Chargers in Inglewood, Calif., giving Mike LaFleur a victory in his head coaching debut over Jim Harbaugh.

The Chargers were 9 1/2-point favorites — biggest in the NFL in Week 1 — but they played from behind the entire game.

LaFleur became the first Cardinals coach to win his debut since Don Coryell in 1973. Coryell coached the Chargers from 1978-86.

LaFleur won in the same SoFi Stadium where he worked his final game as the Los Angeles Rams’ offensive coordinator last year before being hired by Arizona in February. He added 16 new assistants and 18 new players.

Chad Ryland had four field goals as the Cardinals won on the road against the Chargers for the first time since 2001. He only miss was a 54-yarder when the ball hit the right upright in the second quarter.

The Cardinals were coming off an injury-riddled season during which they won just three games.

The Chargers made a mess of the fourth quarter. On their first three possessions, they had a blocked punt, Justin Herbert was intercepted and Los Angeles turned the ball over on downs on fourth-and-goal from the 3-yard line. They had another turnover on downs with less than 2 minutes remaining.

Herbert was 17 of 27 for 209 yards with a touchdown and an interception, and was sacked three times.

The Cardinals dominated possession, 37 minutes to 22, and ran 72 plays to 51 for the Chargers and compiled 393 yards of offense to 268.

Arizona dominated the first half and scored on its first possession. Jeremiyah Love, the No. 3 overall pick, stiff-armed Cam Hart in the left corner of the end zone and scored on a 5-yard run.

Harbaugh lost to open his third season as Chargers coach. The team won 11 games and made the playoffs in each of his first two years.
