Lewis said he would like to coach, but it's not as simple as Brown extending an offer and Lewis accepting.
"It's more complicated than that," Lewis said.
Lewis, whose contract is expiring, said he and Bengals owner Mike Brown will have a talk on Monday morning and go from there. Multiple Bengals players said they don't know what Lewis' future holds, and his assistants seem in the dark as well.
Although Lewis and Brown talk every day, Lewis has maintained that his future has not been a topic of discussion, and a decision is not necessarily expected by Monday. Lewis currently has his end of the season media conference scheduled for Monday at noon ET.
ESPN's Adam Schefter reported Dec. 17 that Lewis and the Bengals plan to part ways after the season, although Schefter more recently reported on Sunday morning the possibility of Lewis returning was not out of the question.
Lewis seemed somewhat emotional when addressing the media following the win in Baltimore. Lewis spent several years as a defensive coordinator there and has said many times that it is a place that still means a lot to him.
"I wouldn't be in Cincinnati if it wasn't for them," he said. "I love to come here and they know what they're going to get when I come here. Our guys are going to fight through the end."
Although Lewis seemed emotional at his media conference, multiple Bengals players said Lewis didn't do anything out of the ordinary when addressing the team after the win.
"Marv is always emotional," joked Brandon LaFell. "Y'all just don't see it. He's always emotional. It always looks like he's going to cry. He's definitely emotional, especially beating the team that he coached, beating this franchise that he coached at for so long. I'd get emotional also."
Added linebacker Vincent Rey: "He wasn't emotional with us. I didn't see it. I felt it from other people, I felt it from other coaches, other players, but I didn't feel it from him."
Lewis ended up signing a new deal the last time he was in this situation. Lewis entered the 2010 season without a new contract, and even though that team finished 4-12, he and Brown agreed to an extension after Brown promised to make some changes to the roster and coaching staff. Lewis just concluded his 15th season in Cincinnati and is the second-longest tenured coach in the NFL.
"We don't know anything, it's all speculation at this point, but I couldn't think of a better way to send him off if this is his last game," Bengals quarterback Andy Dalton said.
