Arrieta (hamstring) is set to take the mound against the Brewers on Thursday, Carrie Muskat of MLB.com reports.

EDGE Analysis

The right-hander will make his first start since facing the Pirates on Sept. 4, which was the game Arrieta was forced to exit due to right hamstring tightness. Looking ahead to Thursday's outing, Arrieta will be kept on a 75-to-80 pitch limit as he makes his return to the mound, although upcoming starts should see him proceed without any sort of restriction. On the year, he's compiled a 3.48 ERA and 1.20 WHIP over 28 starts.

Arrieta (hamstring) is expected to start the Cubs' series opener with the Brewers on Thursday, but said that he'll be scheduled to throw around 75-to-80 pitches, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

The Cubs were pleased with how Arrieta looked during his 25-pitch bullpen session Tuesday, but because the right-hander hasn't taken the mound for a game since Sept. 4, it's expected that he'll eased back into the fold with an abbreviated outing Thursday. That could limit Arrieta's appeal in DFS contests since it's less likely that he comes out of the start as the pitcher of record, but even if he only tosses four or five innings, that may be enough for season-long owners to justify activating him. Assuming he toes the rubber Thursday, Arrieta would line up for two more starts before the regular season ends, and isn't likely to face as restrictive pitch counts in those outings.

Arrieta (hamstring) said he's hopeful to start Thursday against the Brewers, Jesse Rogers of ESPN.com reports.

EDGE Analysis

Arrieta came through a light bullpen session with no issues Tuesday, and if he checks out Wednesday, the 31-year-old will rejoin the Cubs' rotation for Thursday's series opener against the Brewers. If he does start Thursday, Arrieta would likely be able to make two additional starts beyond that before the regular season ends. He would likely be on a pitch limit in his first start back.

Arrieta (hamstring) will throw a light bullpen session Tuesday before determining when he will rejoin the Cubs' rotation, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

The Cubs will wait and see how Arrieta's hamstring responds Wednesday before confirming when his next start will be. If all goes well, he'll likely return to the mound during the Cubs' upcoming series against the Brewers.

Arrieta (hamstring) threw a successful 42-pitch bullpen session Saturday, Bruce Levine of 670TheScore.com reports.

EDGE Analysis

Everything apparently went off without a hitch, but the Cubs will wait and see how Arrieta responds Sunday before determining when he'll return to the mound for the big club. If he checks out, Arrieta is expected to pitch in one of Chicago's pivotal games against the Brewers in Milwaukee next weekend. He owns a 3.48 ERA and 1.20 WHIP across 160.1 innings this season.

Arrieta (hamstring) will toss another bullpen prior to Saturday's game, Jesse Rogers of ESPNChicago.com reports.

EDGE Analysis

This side session will determine the next step for Arrieta, as a timetable for his return to the mound will be established by the end of the weekend following his second bullpen in three days. The plan remains for the right-hander to take the mound in a pivotal series against the Brewers in Milwaukee next weekend if he's cleared. Throughout the course of the 2017 season, Arrieta is sporting a 3.48 ERA and 1.20 WHIP over 160.1 innings.

Arrieta (hamstring) threw an abbreviated bullpen session Thursday, Gordon Wittenmyer of the Chicago Sun-Times reports.

EDGE Analysis

This is an encouraging sign, as it marks the first time Arrieta has thrown from a mound since injuring himself Sept. 4. He reported feeling good after the light session, but the Cubs will wait to see how his injured hamstring responds Friday before determining his next step. If the 31-year-old checks out, he's expected to toss a full bullpen session over the weekend and then travel with the team. Barring any setbacks, Arrieta could potentially rejoin the Cubs' rotation next weekend against the Brewers.

Arrieta (hamstring) could throw a bullpen over the weekend after playing catch Thursday, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Arrieta has been throwing on flat ground all week, and if he checks out on Friday, the plan is for him to toss a full bullpen session over the weekend and then travel with the team. If all goes well, he could return to the rotation next weekend against the Brewers.

Arrieta (hamstring) threw on flat ground again Tuesday, Gordon Wittenmyer of the Chicago Sun-Times reports.

EDGE Analysis

The Cubs have not set a date for his first bullpen session since his injury, and that means a return the next time through the rotation is off the table. A return for next weekend's series in Milwaukee (Sept. 22-24) seems like a best-case scenario for Arrieta, who is dealing with a Grade 1 hamstring strain.

Arrieta (hamstring) was able to play catch Sunday but remains without a firm return date, Carrie Muskat of MLB.com reports.

EDGE Analysis

Arrieta suffered a hamstring injury during his Sept. 4 start, but was only projected to miss 1-to-2 turns through the rotation while rehabbing his injury. He missed his first scheduled start this weekend and it appears he won't be able to return to the rotation this week, either. We should get a picture of his current physical condition once he's able to begin throwing at high intensity again. His situation remains fairly fluid moving forward.
