Unfortunately, Mobley didn't catch the Browns' finest performance.
Kyler Murray threw for four touchdowns to lead the Cardinals to a 37-14 victory, matching their best start to a season (6-0) since 1974. Murray connected on two touchdowns with DeAndre Hopkins, and one each to A.J. Green and Christian Kirk.
James Conner added 71 yards on the ground for the Cardinals.
With Mobley in the house, the Browns largely struggled throughout the afternoon. They trailed 28-0 to start the game, and even had an injury scare with quarterback Baker Mayfield, who left briefly with a shoulder injury. He was in a sling after the game but said he'd play on Thursday.
After taking in the Browns game on Sunday, Mobley will now look ahead to the start of the regular season with the Cavaliers. The team will get things started on Wednesday with a road matchup against Ja Morant and the Memphis Grizzlies.
Mobley averaged 8.4 points, 7.6 rebounds and 1.6 assists in the preseason.
