Production on the series was suspended last month when Sheen, 44, announced he would be entering rehab as a "preventive measure." The nature and location of Sheen's treatment is unknown.
The rehab stint came almost two months after the Emmy-nominated actor's Christmas Day arrest, when he was charged with second degree assault, menacing and criminal mischief after a heated argument with wife Brooke Mueller. Sheen is due back in court on March 15.
Two and a Half Men has remained a ratings winner for CBS despite Sheen's personal turmoil. The series' most recent new episode was the evening's top-rated program, attracting 17.5 million viewers and hitting a seaso high among adults 18-to-49. The show has already taped 18 of the 24 episodes ordered for the season.
