Nationals interim manager Miguel Cairo said Friday that Ruiz (concussion) has started participating in baseball activities, but the Nationals plan to ramp up his workload slowly, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Ruiz landed on the 7-day concussion injured list July 8, and Washington is taking a cautious approach with his return to the active roster. Ruiz doesn't have an official target date for his return and should be considered week-to-week as he continues to ramp up his baseball work.

The Nationals placed Ruiz on the 7-day concussion injured list Tuesday, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Ruiz originally landed on the concussion IL on June 27 after being hit by a foul ball while in the dugout. He was activated Friday, but renewed symptoms will force him to remain on the injured list through the All-Star break. Riley Adams will take over as the Nationals' backstop for now, and Drew Millas will come up from Triple-A Rochester to provide some depth behind the plate.

Ruiz is out of the lineup for Sunday's game against the Red Sox.

EDGE Analysis

Ruiz will get a breather after he returned from the 7-day injured list Friday and started behind the plate in the first two games of the series with Boston, going 2-for-8 with an RBI. Riley Adams will step in as the Nationals' catcher Sunday.

The Nationals reinstated Ruiz (concussion) from the 7-day injured list Friday.

EDGE Analysis

The 26-year-old landed on the concussion IL on June 24 after being struck by a foul ball while in the dugout, but he's back on the active roster after missing little more than a week.

Ruiz was moved to the 7-day injured list Friday after being diagnosed with a concussion, Spencer Nusbaum of The Washington Post reports.

EDGE Analysis

Ruiz was struck by a foul ball while in the dugout during Monday's game against the Pirates. He was initially placed on the 10-day injured list Tuesday, but he was diagnosed with a concussion after seeing a specialist. By shifting to the 7-day IL, Ruiz is eligible to return Tuesday as long as he clears the league's concussion protocols.

The Nationals placed Ruiz on the 10-day injured list Tuesday due to a head contusion.

EDGE Analysis

A foul ball connected with Ruiz's head during Monday's contest, though after evaluation, it seems he managed to escape the incident with only a bruise. Riley Adams will take over as the Nationals' primary catcher while Ruiz is out, and Drew Millas will come up from Triple-A Rochester to provide depth behind the plate.

Ruiz (head) was taken to a local hospital for a CT scan after leaving Monday's game against the Padres, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Ruiz was removed from Monday's game against the Padres after suffering an apparent head injury, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Ruiz was in the dugout when he was struck by a foul ball off the bat of teammate Josh Bell in the top of the fourth inning. Ruiz was later replaced by Riley Adams.

Ruiz is not in the Nationals' starting lineup against the Dodgers on Friday.

EDGE Analysis

Ruiz -- who went 1-for-12 over his last three starts -- will get a breather for Friday's series opener. Riley Adams will serve behind home plate and bat eighth while catching pitches from Nationals southpaw MacKenzie Gore.

Ruiz is out of the lineup for Monday's game against the Rockies.

EDGE Analysis

Ruiz remains the Nationals' No. 1 backstop, but he's been sitting against left-handed starting pitchers more frequently of late while manager Dave Martinez looks to keep backup catcher Riley Adams involved. Adams will be behind the plate Monday as the Nationals face off against southpaw Carson Palmquist, but Ruiz will likely re-enter the lineup Tuesday versus righty Antonio Senzatela.
