Josh McCown and the Cleveland Browns (1-2) will be looking for a Week 4 upset against Philip Rivers and the reeling San Diego Chargers (1-2) in an NFL 2015 season match at the Qualcomm Stadium on Sunday.

Cleveland lost their Week 3 game against an inspired Oakland Raiders, 27-20, as Johnny Manziel goes back to the bench for the 36-year-old veteran signal caller, as per Bleacher Report.

The Browns' flimsy offensive line didn't help their cause as they let the Raiders' defense sack McCown five times in the match.

Meanwhile, the Chargers are on a two-game losing streak after their 31-14 blowout loss to the Minnesota Vikings last Sunday, via Fansided.

Perhaps their first home game in three games would help rejuvenate Mike McCoy's squad as Rivers regain his confidence in front of hometown fans.

San Diego's offensive line also needs much improvement as they allowed the Vikings to sack Rivers four times during their match.

Cleveland is so far struggling against running back plays and so Melvin Gordon could be the key to San Diego's victory this weekend.

Prediction: Chargers win, 31-21.
