The Rockies selected Kauffmann's contract from Triple-A Albuquerque on Friday.
Kauffmann will make his major-league debut Friday against the Rangers. The 25-year-old righty holds a 7.78 ERA and 1.78 WHIP through 37 innings in Triple-A across eight starts, and he's unlikely to offer much fantasy relevance. To make room for Kauffmann on the roster, the Rockies optioned Riley Pint to Albuquerque on Wednesday and transferred German Marquez (elbow) to the 60-day injured list Friday.
