The Colorado Rockies can't quite seem to get everyone back on their feet this season, and this week has been no exception. First Jorge De La Rosa cut short his latest minor league rehab assignment due to fluid build up in his surgically-repaired left elbow, then Juan Nicasio twisted his knee in a game against the Dodgers on Saturday. According to Patrick Saunders of the Denver Post, De La Rosa will be out "at least a week" but the team doesn't think it will be a long-term issue, while Nicasio is headed to the 15-day disabled list and will undergo an MRI on Tuesday.

In the meantime, RHP Guillermo Moscoso will replace Nicasio on the roster. The 28-year-old has appeared in two games this season, ceding 12 run and 16 hits in just 9.1 innings and posting 10 strikeouts in the process.
