Trainer Todd Pletcher and co-owner Mike Repole were seen speaking with a state-commissioned veterinarian after Forte’s morning workout. 

Forte is the fifth horse scratched from the Derby, and the race is now set to be run with 18 horses. It would be the smallest field to run at the Kentucky Derby since 2020, when just 15 horses ran, according to ESPN.

Practical Move, Lord Miles, and Continuar were all scratched on Thursday, with Skinner scratched on Friday due to an elevated temperature.

"After evaluating the colt upon my arrival, I feel that he has not been able to reach the peak fitness required to take on a race as tough as the Kentucky Derby," said Continuar trainer Yoshito Yahagi, according to the Courier Journal.
