The Rockies will select Hudson's contract from Triple-A Albuquerque and have him start Saturday's game against Atlanta, Patrick Lyons of JustBaseball.com reports.
The loss of Ryan Feltner (shoulder) created an opening in Colorado's starting rotation, and Hudson will be the choice to fill the gap until Feltner is able to return. The 29-year-old has started 17 games for the Rockies this season, but he was outrighted to Albuquerque in early July after accumulating a 5.84 ERA and 1.64 WHIP, both of which represent the worst marks of his seven-year MLB career. Cal Quantrill, who was originally slated to start Saturday's game, will have his next start pushed back to Colorado's next series in Arizona.
