Cuthbert was designated for assignment Friday by the Royals, Rustin Dodd of The Athletic reports.
Cuthbert was added to the 40-man roster at the end of November after signing a one-year contract, but he's since been designated for assignment following the return of Kyle Zimmer. Cuthbert could still earn his spot back in spring training, but he'll likely begin the year at Triple-A Omaha.
