The move was made Saturday, a day before Detroit hosts the St. Louis Blues.
Detroit drafted Sheahan in the first round of the 2010 NHL draft and he played in one game for the Red Wings last year. He had 35 points in 67 games this season for the Grand Rapids Griffins.
Sheahan pleaded guilty to drunken driving in December following an infamous traffic stop. He was wearing the costume of the purple Teletubby named Tinky Winky on Oct. 29 when he was arrested in Grand Rapids, Mich. Police at the time said Sheahan had a blood-alcohol level of 0.30, well over the legal limit.
