Nationals outfielders Bryce Harper and Jayson Werth didn't make the trip for Monday's Grapefruit League game against the Yankees, MLB.com reports.
Harper is battling flu-like symptoms, and should be good to go in a day or two. Werth is dealing with a strained right biceps.
"Bryce wanted to come on the trip," manager Matt Williams said. "I told him to stay back and take it easy. I plan to bring him [to Lake Buena Vista] tomorrow. Jayson is going through his progressions. When we get back, we'll see where he's at."
Harper and Werth comprise two-thirds of the team's projected starting outfield.
