CBS has about six weeks to figure what to do with the show. Two unaired episodes of the series -- TV's No. 1-rated comedy -- are in the can, according to the show's producer, Warner Bros.
Repeats, including Monday night's episode, will be inevitable, and there were rumors that the show's writers were preparing a few episodes without Sheen's girl-crazy character, TV insiders said.
The 45 year old was hospitalized Thursday, reportedly suffering from a hiatal hernia in his stomach following a party with a bevy of women during which he allegedly consumed large quantities of alcohol and cocaine.
If his absence dragged on past mid-March, CBS would have to put another show in its place -- at least temporarily. On paper, "Men" has six more episodes to finish this year and 24 new ones next year.
TMZ reported Monday that the star would remain in a rehab facility for the next three months, derailing the next eight episodes of the show.
During the past summer, Sheen signed a new deal -- at $1.25 million per episode -- that keeps him on the show through the end of next season.
