Jaylen Warren will return to the Pittsburgh Steelers' lineup on Sunday after sitting out their previous game two weeks ago with a knee injury.

Warren being back on the field is seemingly a good thing as the Steelers (3-1) look to build on their AFC North lead when they host the Cleveland Browns (1-4) at Acrisure Stadium.

However, Warren does not have impressive statistics in his first season as a starter. In three games, he has just 132 rushing yards on 43 carries, though he has caught 11 passes for 142 yards and a touchdown.

Meanwhile, reserve running back Kenneth Gainwell had a big game on Sept. 28 when the Steelers beat the Minnesota Vikings. He rushed for a career-high 99 yards and two TDs on 17 carries and had six receptions for 35 yards.

So, how do the Steelers divide the carries this week? It's an interesting question after Gainwell's emergence, considering that Warren is averaging just 3.1 yards per carry this season, down from his career mark of 4.6.

The Steelers have run some sets this season in which Warren and Gainwell have been on the field at the same time. Offensive coordinator Arthur Smith acknowledged the Steelers could do that again Sunday, but didn't tip his hand.

"They're both unique players," Smith said. "They're not, in my opinion, traditional running backs."

Indeed, both Warren and Gainwell can be spread wide in certain formations to take advantage of their receiving skills.

Warren has shown big-play capabilities in the passing game this season, averaging 12.9 yards per catch, including a 65-yard play. Smith is excited to have Warren.

"Jaylen is a very unique guy," Smith said. "Just his yards after contact, that's an interesting stat. Guys bounce off him. He's got a feel, a guy who can take a checkdown or a schemed-up bubble screen and go 60. That's unique in space."

Smith also thinks highly of Gainwell, who signed with the Steelers as a free agent in the offseason after spending his first four seasons with the Philadelphia Eagles.

"He's just a unique athlete," Smith said.
