The Pittsburgh Steelers suffered a disappointing 25-10 loss to the Los Angeles Chargers on Sunday. The nature of their fourth defeat of the season has former Detroit Lions quarterback Dan Orlovsky worried.The Steelers' lead over the Baltimore Ravens (4-5) in the AFC North has been cut in half after Sunday's defeat. Pittsburgh's defense has been a weak link for the team this season, but the offense, somehow, was worse against the Chargers (7-3).Following the defeat, Dan Orlovsky sent a warning to the Steelers (5-4) and their fans on X:"Last night should worry Steelers and their fans."The Steelers had just three points in the game before their final drive, which made the score 25-10. Pittsburgh has lost three of its last four games and are one game ahead of the Ravens, who are launching a late charge for the postseason with Lamar Jackson returning to the fray.Quarterback Aaron Rodgers had a poor game, completing 16 of 31 attempts for 161 yards, one touchdown and two interceptions."I expect to play great every single week, and this was not my best performance," Rodgers said. "I got to play better. Whatever it takes. If it’s better checks, if it’s better throws."Whatever it is, I got to play better. We got to bounce back. We got a division opponent next week (hosting the 3-6 Cincinnati Bengals). We’re 5-4, we’re ahead by a game in the division. We got to play better on offense for sure."Steelers coach Mike Tomlin confident in team's ability to play better after Chargers lossThe Steelers' third loss in four games has sparked criticism from analysts and fans. However, Pittsburgh coach Mike Tomlin is not sweating over the loss and sent a warning to other teams."We'll be better," Tomlin said after the game. "We have to be, but we certainly weren't tonight."The Steelers will host the Cincinnati Bengals on Sunday before travelling to Soldier Field to take on the Chicago Bears (6-3) the following week.
