Kelley left Monday's game against the Giants with an apparent arm injury, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

It's unclear if Kelley suffered a significant injury, but he left with the team trainer after spiking a pitch in the dirt. This could be cause for concern, considering he dealt with bone chips in his throwing elbow last year. The 33-year-old's status should be updated after further evaluation following the conclusion of Monday's matchup.

Kelley rejoined the Nationals on Monday after he was away from the team to tend to a personal matter, Chelsea Janes of The Washington Post reports.

EDGE Analysis

Kelley has already logged five appearances in spring training, so his brief time away from the team won't jeopardize his availability for the start of the season. The right-hander is scheduled to pitch in Monday's Grapefruit League game against the Marlins.

Kelley (forearm) tossed a 1-2-3 inning in Sunday's 9-3 win over the Braves in Grapefruit League play.

EDGE Analysis

Kelley concluded a brutal 2017 campaign on the disabled list after undergoing a stem-cell injection for his throwing elbow, but his strong showing Sunday likely assuaged some of the concern the Nationals may have had about his health heading into the upcoming campaign. According to Jamal Collier of MLB.com, manager Dave Martinez indicated that he was eager to get Kelley in a game early in spring training to ensure the right-hander has several opportunities to gear up for 2018 and perhaps reestablish himself as a dependable contributor in the bridge to closer Sean Doolittle. If Kelley skirts the injury woes that plagued him last season, it wouldn't be surprising if he staged a dramatic turnaround. After all, Kelley was one of the top setup men in the majors as recently as 2016, submitting a 2.64 ERA and 12.4 K/9 rate across 58 innings.

Kelley (forearm) threw his first bullpen session of spring Thursday, Jamal Collier of MLB.com reports.

EDGE Analysis

Kelley noted that his arm felt normal afterwards, which is encouraging given the amount of time he spent on the disabled list last season. Barring any setbacks, the 33-year-old is expected to be fully healthy by the start of the season after receiving a stem cell injection in his elbow earlier back in October. He's looking to bounce back from his injury-riddled 2017 season that saw him post a brutal 7.27 ERA and 1.54 WHIP across 26 innings of relief.

Kelley (forearm) was reinstated from the 60-day DL on Friday.

EDGE Analysis

Kelley's season ended in late September with inflammation in his right elbow, following a rough year which saw the right-hander post a 7.27 ERA and 1.54 WHIP over 26 innings of relief. Looking ahead, Kelley should be ready to get back to business during spring training after receiving a stem cell injection a month ago.

Kelley (elbow) said he expects to be healthy for the start of the 2018 season, Chelsea Janes of The Washington Post reports.

EDGE Analysis

Kelley's season prematurely ended in September after it was revealed that bone chips in his right elbow were causing inflammation. The good news is he seems to have avoided any structural damage, and it doesn't look like he'll require surgery at this point. Kelley opted for a stem cell injection instead, and he'll now wait for the inflammation to subside before hopefully picking up his offseason routine in time to get ready for the start of next season. He was limited to just 26 innings in 2017 due to injuries, compiling an unsightly 7.27 ERA and 1.54 WHIP during that span.

Kelley (forearm) was placed on the 60-day DL on Saturday with bone chips in his right elbow, Chelsea Janes of The Washington Post reports.

EDGE Analysis

This eliminates any chance for a return during the postseason, but it could be worse for Kelley, as it seems the inflammation in his elbow was the result of bone chips and was not related to any kind of structural issue. Kelley has already undergone Tommy John surgery twice in his career.

Manager Dusty Baker said Kelley is dealing with inflammation and nerve trouble in his forearm, Chelsea Janes of The Washington Post reports.

EDGE Analysis

Kelley is set to get more extensive tests done on his arm after exiting Friday's game with an injury. The good news is the issue doesn't appear to be in the Tommy John area, but not much else is known beyond that. An update on his status should be available once his test results are disclosed.

Kelley was removed from Friday's game in the eighth inning after suffering an apparent injury, Jamal Collier of MLB.com reports.

EDGE Analysis

Kelley motioned to trainers after throwing his 20th pitch of the eighth inning. It's unclear what was wrong, but considering Kelley has dealt with neck issues this year and has undergone Tommy John surgery twice in his career, any injury like this is scary. Consider him day-to-day until the Nationals can fully evaluate him.

Kelley (neck) was activated off the 10-day disabled list Thursday, Mark Zuckerman of MASN reports.

EDGE Analysis

The Nationals were dealt a tough blow Thursday with lights-out reliever Ryan Madson landing on the disabled list, but Kelley lessens the sting as he'll add some veteran bullpen depth. That said, Kelley did not look particularly sharp on his recent eight-game rehab stint, notching a 13.50 ERA and a 2.25 WHIP over that stretch. The Nationals will likely turn to Brandon Kintzler for setup duties in front of Sean Doolittle rather than using Kelley in that role.
