Things haven't been easy for Joba Chamberlain since he returned to the majors, but the reliever might not have to worry about that soon.

With CC Sabathia due back from the disabled list on Friday, the Yankees will have to make a roster move to open a spot for their returning ace. According to a source, the team is considering a demotion for Chamberlain, who has struggled badly in his seven appearances.

Chamberlain has minor-league options left, so the Yankees could send him down for 10 days to let him work out the kinks, then bring him back when the minor-league season ends and big-league rosters expand in September.
