Manager Joe Maddon said there's "barely" enough time for Morrow (biceps) to return this season, Paul Sullivan of the Chicago Tribune reports.

EDGE Analysis

Maddon added that the Cubs would be lucky to have Morrow back at full health before the end of the year. The closer, who has been on the shelf since July 19 with a biceps injury, still hasn't been cleared to throw off a mound.

Morrow (biceps) has yet to resume throwing off a mound, Carrie Muskat of MLB.com reports.

EDGE Analysis

Manager Joe Maddon noted that Morrow is still progressing, though he added that there's been no regression. The right-hander is aiming to return sometime during the second half of September, though he'll remain without a concrete return date until he resumes mound work.

Morrow (biceps) is targeting a return in the second half of September, the Chicago Tribune reports.

EDGE Analysis

Morrow has been ramping up his throwing, extending his distance out to 120 feet Friday, but he's still at least a few weeks away from returning. When he gets back, the Cubs will avoid using him on back-to-back days in hopes of preserving his arm for the playoffs, so even if he's able to claw back closing duties from Pedro Strop, who's been a very capable deputy, he won't be receiving every save opportunity.

Morrow (biceps) threw off flat ground again Wednesday, Patrick Mooney of The Athletic reports.

EDGE Analysis

Though Morrow has yet to pitch off a mound, he continued to increase his throwing distance from flat ground, moving up to 105 feet from 60-to-90 feet this past weekend. There's a chance Morrow will advance to mound work within the next few days, but manager Joe Maddon has yet to offer up a concrete timetable for his recovery, so his eventual return date remains uncertain at the moment. Previously, Morrow stated that he would like to pitch in one or two minor league games before returning, but he will need to advance to that step in the near future since the minor-league season is winding down.

Morrow (biceps) still hasn't thrown off a mound, Carrie Muskat of MLB.com reports.

EDGE Analysis

Morrow is reportedly making steady progress and recently resumed throwing off flat ground. He's hoping to resume mound work soon, though he'll remain without a timetable for his return until he does so. Given how close it is to the end of the minor-league season, Morrow will likely have to get back up to speed with simulated games rather than a rehab assignment. Pedro Strop will continue to hold down the ninth inning for now. Joe Maddon added that Morrow may not immediately reclaim closing duties when he rejoins the Cubs.

Morrow (biceps) was sent for more tests on his arm Friday, Carrie Muskat of MLB.com reports.

EDGE Analysis

Morrow has been out since mid-July with right biceps inflammation but had recently begun throwing in the bullpen. It's unclear if a specific setback prompted the tests. For a player with Morrow's lengthy injury history, optimism doesn't seem warranted, though it's difficult to say how his recovery timeline will be affected until the results of the tests are known.

Morrow (biceps) threw a 25-pitch bullpen session Saturday, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Morrow has been on the shelf for nearly a month while dealing with right biceps inflammation. He's made significant progress of late, as he played catch Monday and Wednesday, and he threw 25 pitches off a mound Saturday. Morrow figures to require 2-to-3 more bullpens prior to embarking on a minor-league rehab stint, per Gonzales.

Morrow (biceps) is expected to throw off a mound this weekend, Gordon Wittenmyer of the Chicago Sun-Times reports.

EDGE Analysis

Morrow stated that he's "feeling good right now throwing," and believes the muscled is fully healed, so he's going to continue ramping up activity sometime this weekend. This will mark the first time he's back on the mound since suffering the right biceps injury just after the All-Star break in July. This session will go a long way in assessing his timetable, as the Cubs have yet to chart out a concrete plan for the closer.

Morrow (biceps) played catch Monday and Wednesday, Carrie Muskat of MLB.com reports.

EDGE Analysis

Morrow resumed throwing off flat ground last week, but it doesn't appear he has made much progress in his recovery since that time. The Cubs will have a better idea regarding a target return date for the closer once he's ready to throw off a mound again. While Morrow has been sidelined since July 19, Pedro Strop has established himself as the Cubs' top option for saves.

EDGE Analysis

Though Morrow remains without a definitive timetable for his return, this marked the first time he was able to throw the ball around since landing on the DL on July 19. Expect Morrow to increase his throwing distance within the next couple days before advancing to a bullpen session.
