Herrera was placed on the 10-day disabled list with a torn Lisfranc ligament in his left foot Monday, Dan Kolko of MASN Sports reports.

EDGE Analysis

Herrera had only made two appearances since returning from a shoulder injury before going down again, getting carted off the field while covering first Sunday against the Mets. A recovery timeline has not yet been announced, but if surgery is required he will definitely miss the rest of the season. Ryan Madson (back) was activated in a corresponding move and could take temporary closing duties until Sean Doolittle (toe) returns from the disabled list.

Nationals manager Dave Martinez relayed that Herrera is dealing with a left foot injury and will undergo X-rays later Sunday, Jorge Castillo of The Washington Post reports.

EDGE Analysis

Herrera suffered a serious-looking lower-leg injury when he attempted to cover first base during his appearance in Sunday's 15-0 win over the Mets. He was unable to put any weight on the leg and needed to be carted off the diamond, fueling speculation that he may have suffered an injury to his Achilles' tendon. While Martinez clarified that Herrera didn't sustain damage to his Achilles, a fractured foot apparently hasn't been ruled out just yet. The X-rays should offer more clarity on the extent of Herrera's setback, but even if no structural damage is detected, he could require a stint on the disabled list.

EDGE Analysis

Herrera while attempting to run to first base to record a putout after fielding a grounder. He ended up losing his balance on the way to the bag and was unable to put any weight on his leg after being assisted to the cart. Specifics regarding the extent and nature of the injury should be available soon, but this looks like the sort of setback that will result in another trip to the disabled list for Herrera, who was activated less than a week earlier after recovering from a shoulder issue. Koda Glover and Ryan Madson (back), who is expected to be activated from the DL within a few days, look like the top candidates to close if Herrera is indeed shut down.

Herrera struck out one in a perfect ninth inning Tuesday against the Phillies.

EDGE Analysis

Koda Glover and Wander Suero pitched in the eighth inning as the Nationals led 7-4 while Herrera was held back for what was going to be a save chance before the Nats tacked on three runs in the bottom of the eighth. It was Herrera's first appearance back from the disabled list after a two-week absence due to a shoulder injury. The fact that manager Dave Martinez was willing to turn to Herrera right away makes it clear that Herrera is still the preferred replacement option for Sean Doolittle (toe) in save situations.

Herrera (shoulder) was activated from the 10-day disabled list Tuesday, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Herrera checked out OK after testing his arm prior to Tuesday's game against the Phillies, clearing the way for the reliever to rejoin the Nationals after missing two weeks with a shoulder injury. He should immediately slot back in as the team's interim closer with Sean Doolittle (foot) still on the shelf, likely pushing Koda Glover to a setup role.

Herrera (shoulder) could be activated from the 10-day disabled list during the Nationals' upcoming three-game series with the Phillies, which runs from Tuesday to Thursday, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Herrera apparently checked out fine after tossing a 15-pitch simulated game Saturday and looks like he might be ready to rejoin the Nationals without requiring a rehab assignment beforehand. The Nationals will likely re-evaluate the right-hander Tuesday, and if his right shoulder checks out fine, he could re-enter the team's bullpen mix for the series opener. Manager Dave Martinez might prefer to ease Herrera back into the fold, so he might not immediately recapture closing duties, which have since fallen to Koda Glover.

Herrera pitched a simulated game against live hitters Saturday, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Herrera has been on the disabled list since Aug. 8 due to a right shoulder impingement, and he resumed throwing Aug. 11. It's good news for the Nationals that he's advanced to pitching against live batters, as it means he could return from the shelf in the near future. Herrera might require a quick rehab stint prior to his activation.

Herrera (shoulder) threw Saturday for the first time since heading to the disabled list with a right rotator cuff impingement, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Herrera hit the disabled list Wednesday but is not expected to miss a great deal of time. He appears to be making progress in his recovery on schedule. If he returns before Shawn Doolittle (toe), he could spend a few days as the Nationals' closer, though Doolittle is also about to throw off the mound, so it's unclear who will get back first.

Herrera avoided any structural damage in his throwing shoulder and will refrain from throwing over the next few days, Dan Kolko of MASN Sports reports.

EDGE Analysis

Overall, this was a fairly positive outcome for the Nationals and Herrera after he was diagnosed with a right rotator cuff impingement. He was placed on the 10-day DL on Wednesday and will receive medication for his injury, which will hopefully be able to expedite his return. The club is optimistic that Herrera will resume throwing after 3-to-4 days and that this won't be a long absence.

Herrera was put on the 10-day disabled list due to a right rotator cuff impingement prior to Wednesday's game, Chelsea Janes of The Washington Post reports.

EDGE Analysis

Herrera will miss some time after exiting Tuesday's contest against the Braves with right shoulder tightness. The club deemed his injury as a rotator cuff impingement following an MRI, but failed to offer up a timetable for his eventual return. That said, there's a chance Herrera will require a lengthy absence, which will open up the ninth-inning spot for the time being. Since Sean Doolittle (foot) is also on the DL, look for Ryan Madson to receive an opportunity as the Nationals closer. Koda Glover was recalled in a corresponding move and also figures to get a chance in a late-innings role.
