Dilson Herrera (quad) is unlikely to return before the end of the 2014 regular season.
Herrera suffered a quad strain on Saturday against the Braves and an injury like that usually takes at least two weeks to heal. The 20-year-old second baseman hit .220/.303/.407 with three home runs and 11 RBI in his first 18 major league games.
Juan Lagares (elbow) is done for the season.
Lagares doesn't need surgery for his right elbow sprain, but his rehab for the injury will last into October. The young center fielder batted .281/.321/.382 with four home runs and 13 stolen bases in 116 games this season while playing elite-level defense.
Mike Napoli is not in the Red Sox starting lineup on Tuesday night against the Rays.
Napoli continues to receive regular days off as he battles through a finger injury. Daniel Nava is starting at first base versus Tampa Bay right-hander Alex Cobb.
Ryan Zimmerman is not in the Nationals' starting lineup on Tuesday night versus the Mets.
The Nats are easing Zimmerman back into action after his 55-game absence. Anthony Rendon is also sitting out Tuesday, so it'll be Kevin Frandsen at third base and Asdrubal Cabrera at second base against New York. Bryce Harper is in left field and Adam LaRoche will start at first base.
