McLouth (shoulder) had his team option declined Monday, Mark Zuckerman of CSN Mid-Atlantic reports.

McLouth signed a two-year deal with the Nationals in 2013, but hit just .173 in 2014 before missing the entire 2015 season with a torn labrum. Given his unclear health status and recent struggles at the big league level, the 34-year-old may struggle to find a big league contract in free agency.

Nationals outfielder Nate McLouth, who has been out all season with a shoulder injury, will not return this season, per MLB.com. 

McLouth was also injured for most of the last season, and the report suggests McLouth recently had another procedure on his shoulder.

Nationals outfielder Nate McLouth underwent a second MRI on his surgically repaired shoulder, which showed no further issues, manager Matt Williams said Tuesday. Williams added McLouth, who has resumed his throwing program, "feels better" after receiving a cortisone injection.

“No issues. Everything’s there. Everything’s repaired. Everything’s OK,” Williams said, per The Washington Times. “He just had a setback. When that happens you shut him down and make sure nothing’s going on. Luckily, nothing’s going on."

The Nationals have placed pitcher Erik Davis (elbow), Casey Janssen (shoulder), Nate McLouth (shoulder), Anthony Rendon (knee), Denard Span (abdominal) and Jayson Werth on the 15-day disabled list, retroactive to March 27, the team announced Sunday.

As expected, Nationals outfielder Nate McLouth will start the season on the disabled list while he rests his surgically-repaired shoulder. McLouth has yet to resume throwing, per the Washington Post.

"I can still hit," McLouth said. "But after I would hit, and stopped throwing for a little bit, I would hit and fire it back up to where I couldn't throw. … It's frustrating. There's only so many exercises you can do before you start going crazy."

Nationals manager Matt Williams told reporters that outfielder Nate McLouth's availability for Washington's season-opener is "in jeopardy," according to the Washington Post.

"Right now, it's probably in jeopardy because we haven't been able to get him out there for a number of at-bats and get through a full spring, keeping in mind that he's coming off of a pretty serious surgery," Williams said, per MASN Sports. "So it's a little in jeopardy right now, but we'll continue to work him as if we were trying to get him ready depending on how he feels. We're looking at 15 days from now and him just starting his spring training, you would say he may not be ready in time."

McLouth underwent shoulder surgery back in August, and has yet to take part in a Grapefruit League game. Williams added that McLouth's shoulder still bothers him when he throws. He is not considered to be in for a long rehab process, per the report.

Nationals outfielder Nate McLouth (shoulder) made his spring debut Wednesday against the Tigers. He came off the bench to go 1 for 2 with one run and one strikeout.

However, McLouth still isn't cleared to play in the field as he works his way back from August shoulder surgery, per MASNsports.com.

"It's a fairly lengthy rehab, so next week we'll look to get him in the game defensively," Williams said. "He feels good about his swing right now. He's excited."

Nationals outfielder Nate McLouth is getting towards the end of his throwing program to rehab his injured shoulder, reports MLB.com. But, manager Matt Williams doesn't want to take any chances with the injury flaring back up for McLouth.

"Once he gets sore, then we got to shut him down for a few days," Williams said. "So we don't want to get there."

McLouth is recovering from shoulder surgery that took place in August to repair a torn labrum. He is getting close to adding more distance to long toss.

"It doesn't hurt, and nothing I've done has made it hurt at all," McLouth said. "So it's fine. Now it's just a matter of getting more distance."

Nationals manager Matt Williams said Thursday the team will take a cautious approach with outfielder Nate McLouth, who has started a throwing program coming off shoulder surgery in August.

"If we were to say at the end of this week that we're going to play a game and Nate was going to go two innings, we probably wouldn't do that at this point because he has got to go through that progression," Williams said, per MASNsports.com. "What that timeframe depends on is how he feels. You can look at the big picture and say well, you need X amount of rehab for this particular surgery. Everybody is different, of course. But we want to make sure that when he's ready to play, he's ready, because we don't want a setback.

"That being said, he's going through the progression of all of his throwing, he's hitting right now. He doesn't have an issue with that. It's going to get sore, we know it. So there's going to be days where he's going to have to just shut it down for that particular day. Which is frustrating because you want to play. We'll get through spring training with him and kind of monitor him on an everyday basis to see where he is at and act accordingly."

Nationals manager Matt Williams told reporters that everyone arrived at camp as of Wednesday. He said that Nate McLouth (shoulder) and Jayson Werth (shoulder) will be limited on Thursday, and Denard Span (hernia) will be a "full-go," per the Washington Times.

Nationals outfielder Nate McLouth is not 100 percent yet, according to NatsInsider.com.

McLouth was shut down in August due to the injury, and had season-ending surgery to repair his labrum. McLouth has been able to take part in drills, but said it's a matter of ramping up his activity. "The thing I still have to work up to is the endurance, the volume," he said. "I’ve been swinging fine, throwing fine. But when you get down here and start getting into the season, the volume just increases, the intensity."

McLouth added that he's happy with the way his shoulder feels thus far. While he may be restricted early, McLouth believes he should be cleared shortly after spring games begin. 

McLouth hit .173 over 139 at-bats before he was shut down.

"I saw a doctor [Friday] here, and he said it’s looking pretty good."

The Nationals have activated Nate McLouth and Taylor Jordan from the 60-day disabled list Friday.

Players can't remain on the 60-day DL throughout the offseason, so the moves were expected. McLouth had surgery on his labrum in August. Jordan spent most of the season injured before undergoing arm surgery in October.
