Las Vegas police investigating allegations fan struck Arizona Cardinals QB Kyler Murray

 A fan allegedly hit Cardinals quarterback Kyler Murray during celebrations of Arizona's 29-23 overtime victory over the Raiders, according to Las Vegas police, who said they are looking into the claims on Monday.

After Byron Murphy Jr.'s game-winning fumble return on Sunday, Murray was giving high fives to spectators in the front rows of Allegiant Stadium when a man suddenly appeared to reach out and strike Murray in the face.

Murray was seen on camera appearing surprised but unharmed before attempting to find the accused attacker in the largely joyful audience.

A battery complaint was filed at the stadium at around 6:30 p.m., according to Las Vegas police spokesperson Officer Larry Hadfield. The report wasn't available right away.

Hadfield did not specifically identify Murray as the reporter, but he did confirm the claim that "a stadium spectator struck a professional football player."

Hadfield stated that no suspect had been located at the time and that an investigation was still ongoing. Mark Dalton, a Cardinals spokesperson, declined to comment on Monday.

In the final 8:13 of regulation, Murray had a tremendous game, guiding the Cardinals (1-0) to two touchdowns and two 2-point conversions to force overtime.

The victory was Arizona's first since Murray agreed to a $230.5 million, five-year contract extension. He was the No. 1 overall pick in the 2019 draft after winning the Heisman Trophy at Oklahoma in 2018.
