NFL: Los Angeles Chargers come back to beat Cleveland Browns

Justin Herbert and the Los Angeles Chargers continued to show their Super Bowl credentials in NFL Week 5 on Sunday, claiming an entertaining 47-42 victory over the Cleveland Browns.

Chargers come out on top of topsy-turvy clash

The lead changed hands seven times as Herbert and Browns quarterback Baker Mayfield led their teams downfield almost at will, but the Chargers (4-1) scored last and the Browns (3-2) could not respond on Sunday.

Herbert continued building his MVP case as he went 26-of-43 passing for 398 yards and four touchdowns with no interceptions and ran for another score. 

The Chargers trailed 27-13 after a spectacular 52-yard touchdown run by Nick Chubb on the opening drive of the second half, but Herbert led them back to take a 28-27 lead and the teams exchanged touchdowns from there. 

Los Angeles thought they had tied the game when Herbert hit Austin Ekeler for a 19-yard touchdown with 3:15 to play but Tristan Vizcaino missed his second extra point of the game to leave the Chargers trailing by a point. 

The Browns went three and out on the next possession and Herbert led the Chargers to the three-yard line, where the Cleveland defence helped Ekeler cross the goal line on purpose with 1:31 to play so the Browns could get the ball back. 

But Mayfield could not finish the job, throwing three successive incompletions from the Cleveland 47-yard line to give the Chargers the ball and end the game. 

Cardinals continue perfect start to NFL season

The Arizona Cardinals improved to 5-0 and remain the only unbeaten team in the NFL after pulling out a 17-10 win against the San Francisco 49ers. 

Kyler Murray's explosive Arizona offence entered the game averaging 35 points per game but had to scrape out the win as they were out-gained 338 to 304 by Trey Lance and the 49ers (2-3). 

Murray completed 22 of 31 passes for 239 yards and a key nine-yard touchdown pass to DeAndre Hopkins with 5:13 to play that effectively put the game out of reach. 

Rookie quarterback Lance made his first start for San Francisco and completed just 15 of 29 passes for 192 yards with an interception, though he led all rushers in the game with 89 yards on the ground. 

Cowboys see off injury-hit Giants in Dallas

The Dallas Cowboys took advantage of injuries to the New York Giants' two most important players on offence, rolling to a 44-20 home victory. 

The Giants lost quarterback Daniel Jones to a concussion and running back Saquon Barkley to an ankle injury and were outscored 27-7 after Graham Gano hit a field goal on the first drive of the second half. 

Dak Prescott completed 22 of 32 passes for 302 yards and three touchdowns for Dallas, while Ezekiel Elliott ran for 110 yards and a score.
