Sources tell PEOPLE at least two men from Ali Fedotowsky's season of The Bachelorette have been "in serious talks" with ABC.
Cape Cod landscaper Chris Lambton and Nashville medical salesman Ty Brown have had offers extended to them to be the next Bachelor, but neither has confirmed yet, a source says.
With the new season of The Bachelor slated to start production later next month, a source tells PEOPLE that while producers have negotiated with both Lambton and Brown, "there may be one or two other men still under consideration."
Last season's Bachelorette garnered the franchise its highest ratings since 2004 when Trista Rehn accepted a proposal from Colorado firefighter Ryan Sutter. Wanting to build upon that, "they are reviewing all avenues carefully," the source says.
ABC and Warner Horizon, who produce The Bachelor, decline to comment on casting speculation.
"We will be making an announcement soon," a spokesperson tells PEOPLE.
