Gray (foot) threw 36 pitches in a simulated game Tuesday and expects to throw another simulated game prior to embarking on a rehab assignment, Thomas Harding of MLB.com reports.
Harding also reports that Gray fielded groundballs and threw to bases, which bodes well for the health of his foot. However, the Rockies' ace said that he anticipates needing two rehab starts before returning, although the team may require three. This pushes his return date to the end of the month, which would ultimately culminate in over a two-month absence due to the issue.
