The Royals placed Lugo on the 7-day concussion list Friday.
Lugo was struck in the forehead by a line drive during Wednesday's game against the Rangers. The good news for Lugo was that a subsequent CT scan came back negative, but he's now in the league's concussion protocol and will need to hit multiple checkpoints before being cleared to return to the majors. In a corresponding move, the Royals recalled Eli Morgan from Triple-A Omaha.
