Wilson has been sidelined since suffering a meniscus tear and bone bruise in his right knee in their preseason opener, with veteran QB Joe Flacco stepping in during his absence.
Wilson, who was pick two in the 2021 NFL Draft, is expected to come immediately back in as starting QB when healthy.
"I'm expecting [him back], but until the doctors say so, I'm just going to say he's being evaluated," Saleh told reporters.
Flacco had a poor game with two interceptions, two fumbles and four sacks against the Bengals.
"It's frustrating," Saleh said. "Any time you turn the ball over and you only get one takeaway, obviously you're not going to win the football game."
Fans became increasingly frustrated at Flacco, with boos heard at MetLife Stadium following a few throwaways, while there were chants for back-up QB Mike White to come on.
Saleh insisted he never considered a QB change, while Flacco said he had no time to worry about it.
"Fans want to see you win football games," Flacco said. "You get the frustration, but it was a two-score game.
"If we put one in the end zone there ... we have more important things to worry about than listening to that stuff."
On the quarterback situation, Flacco added: "We'll see. You guys know more than I do. I'm going to keep my head down and keep working, doing all I can for this team in whatever role that may be."
