Hicks has not played since Aug. 3 because of a right elbow flexor strain. Sabathia missed the Division Series sweep of Minnesota with a sore pitching shoulder.
"We'll have some tough decisions here over the next 24 hours as we work this out, what kind of makes the most sense," Yankees manager Aaron Boone said Thursday.
New York used the same starting lineup in all three games against Minnesota, only the second time this year Boone has done that in three straight games. The Yankees open the ALCS on Saturday against Houston or Tampa Bay.
If Hicks started in center, Brett Gardner could shift to left and Giancarlo Stanton to designated hitter, a move that would send Edwin Encarnacion to the bench. Or Stanton could remain in left and Gardner shift to the bench, especially against a left-handed starter.
Hicks' lack of playing time the last two months is a factor in the decision.
"The good thing is that he's put himself in this position to make a decision," Boone said. "Obviously as good a player as he is, that's exciting."
Sabathia, a 39-year-old left-hander retiring after the season, threw a bullpen session Thursday.
"He out there stretching today now and will play catch and everything," Boone said. "Just talking to him when he came in, said he felt good. You know, so far encouraging."
His lefty relief spot was taken in the Division Series by Tyler Lyons, who pitched a perfect inning in Game 2.
