Nationals manager Dave Martinez said Monday that Cavalli (elbow) is dealing with the flu and will be held back for a few days during his minor-league rehab assignment, Bobby Blanco of MASNSports.com reports.
Cavalli moved his assignment Friday to High-A Wilmington and struck out three over three scoreless innings as he continues to work his way back from the Tommy John surgery he underwent last spring. The illness isn't a long-term concern for Cavalli, and he'll likely be back on the mound with Wilmington or another affiliate in the near future.
