Darvish will undergo an MRI on his shoulder after leaving his Sunday rehab start after just one inning, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Darvish had made one rehab appearance back in late June but was shut down after experiencing similar discomfort. He hopes that he'll pitch again this season, but that's suddenly a doubt after it looked like he was finally back on the right track. His prognosis should become clearer following the MRI.

EDGE Analysis

Darvish was supposed to throw at least 50 pitches but left after throwing just 19, motioning as if something was wrong while warming up for the second inning. It's unclear what exactly went wrong, but this appears to be the latest in a string of setbacks for the veteran starter.

EDGE Analysis

As expected, Darvish will begin a rehab assignment this weekend. He's continued to play catch in the outfield the past couple days after firing a three-inning simulated game Tuesday. Look for him to require a few outings in the minors before being activated from the DL.

EDGE Analysis

Manager Joe Maddon stated that the organization isn't quite sure where to send Darvish yet, or how many rehab outings he will require before being ready to return from the 60-day DL. Darvish was able to toss a three-inning simulated game Tuesday, which following a live batting practice session last weekend. Since the club has allowed Darvish to take all the time he needs to get back to full health, expect the right-hander to appear in multiple games at the minor-league level over the next couple weeks before returning to Chicago's rotation.

EDGE Analysis

Darvish struggled a bit with his command, but the session was overall a positive one, as it was the longest he's thrown so far in his latest recovery. Assuming he feels good Wednesday, his next step will likely be a rehab assignment, Carrie Muskat of MLB.com reports. Given the length of his absence, which began back in late May, Darvish will likely require several rehab appearances, putting his return date sometime in late August or early September.

EDGE Analysis

The Cubs previously reported Darvish's session would be Sunday, but later clarified the correct day to be Tuesday. The veteran right-hander has been throwing bullpen sessions and live batting practice over the last couple weeks but it remains unclear when he's likely to begin a rehab assignment.

EDGE Analysis

Darvish was recently moved to the 60-day disabled list, having been out of action for over two months. He has thrown several bullpen sessions and simulated games in recent weeks, but it remains to be seen when he'll head out on a rehab assignment.

Darvish (shoulder) was put on the 60-day disabled list Friday, Bruce Miles of the Daily Herald reports.

EDGE Analysis

This was merely a procedural move in order to make room for the recently-signed Jorge De La Rosa on the 40-man roster, as Darvish has already spent over 60 days on the shelf. Looking ahead, Darvish is expected to toss another simulated game in the next couple days after throwing a 31-pitch session Wednesday.

EDGE Analysis

Manager Joe Maddon said everything went off without a hitch during Darvish's 33-pitch simulated outing Wednesday. Assuming the right-hander checks out OK in the coming days, he'll toss another simulated contest with an increased pitch count before potentially heading out on a minor-league rehab assignment thereafter.

EDGE Analysis

Darvish was able to get through two innings of work without experiencing any issues, which marks yet another step forward as he continues to recover from a shoulder impingement. Prior to this little outing, he threw a 55-pitch bullpen session last weekend, so he shouldn't be too far off from heading out on a rehab assignment.
