According to sources confirmed by ESPN, there is uncertainty surrounding the availability of Pittsburgh Steelers' running back Jaylen Warren for the team's season opener. The star player suffered a hamstring injury during the first half of Saturday's preseason game against the Buffalo Bills and was unable to return to the field.

Although Steelers coach Mike Tomlin did not provide an official update on Warren's condition immediately after the game, he mentioned that the third-year running back would undergo evaluation in the upcoming week. This evaluation will likely determine the extent of Warren's injury and the duration of his absence from the field.

With the Pittsburgh Steelers set to visit the Atlanta Falcons in Week 1 on September 8, there is growing concern about Warren's availability for the crucial early-season matchup. If Warren is unable to play, rookie Najee Harris, who was the team's first-round draft pick, is expected to step up and have an increased workload in the running back position. Additionally, veteran Cordarrelle Patterson may also see more opportunities at running back.

The Steelers' offensive struggles were evident in their 9-3 loss to the Buffalo Bills on Saturday. As they prepare for the start of the regular season, they will face another setback with the absence of center Nate Herbig, who is currently sidelined with a torn rotator cuff. This further underscores the importance of having a healthy and reliable running back like Warren in their lineup.

Warren, 25, had an impressive season last year, rushing for a total of 784 yards and four touchdowns with an average of 5.3 yards per carry. He also made a significant impact in the passing game, hauling in 61 receptions for 370 yards - the second-highest on the team.

As the Pittsburgh Steelers await further updates on Jaylen Warren's hamstring injury, fans and the coaching staff hope for a speedy recovery for the talented running back. His presence on the field will be crucial as the team aims for a successful start to the season against the Atlanta Falcons.
