Ocon was set to hand over his spot at Alpine to Doohan for the 2025 season, but the Aussie young gun might make his debut at next weekend's season-ender.
According to widespread reports, Ocon will depart Alpine early to join Haas for the post-season test.
Alpine boss Oliver Oakes addressed the rumours on Sunday, telling reporters that while no decision had been made, discussions were taking place.
"I don't think there's been a definitive answer yet, but it has been talked about," Oakes said. "It's obviously slightly complex because, as much as he is ours, he's obviously contractually a Mercedes junior as well, and obviously he'd like to be released early as well."
"I guess you could say it's good to get Jack in early. I think you could say from Esteban's side it's good to move on early," Oakes said.
"I think it suits everybody. So I think the discussion is quite natural, really."
