why is jaylen warren not playing

Jaylen Warren is not playing because he is dealing with a knee injury. He was added late to the injury report with a knee issue and after Saturday's practice, he did not feel right, leading the Pittsburgh Steelers to hold him out of the Week 4 game against the Minnesota Vikings in Dublin, Ireland. This injury appears to be managed with caution by the team, and although it has caused him to miss this game, it does not seem to have long-term implications. The Steelers will rely on other running backs such as Kenneth Gainwell, Kaleb Johnson, and Trey Sermon in his absence. Warren is expected to be back after the team's upcoming bye week and should be ready for the game against the Cleveland Browns on October 12, 2025.
