Righty reliever Chad Qualls, who has been battling a right forearm strain, threw live batting practice in Scottsdale, Ariz., on Wednesday. He will join the team in Denver and throw Saturday at Coors Field, then Black plans to send him on a Minor League rehab assignment.
Righty Jairo Diaz also threw in Scottsdale on Wednesday, and will stay there for "a short period of time" before beginning his rehab assignment.
Black said first baseman Ian Desmond (fractured left hand) and catcher Tom Murphy (fractured right forearm) will undergo tests Monday in Denver to assess how the bones are healing.
