Manager Torey Lovullo said after Sunday's game against the Astros that Perdomo (head) is not in the concussion protocol, Jack Sommers of SI.com reports.
A scary incident unfolded in the third inning Sunday, when a ball off the bat of teammate Ketel Marte struck Perdomo in the helmet as Perdomo was running the bases. It seems he avoided a concussion, and further, Lovullo indicated the shortstop will be in the lineup right away Monday in Kansas City without missing a start.
