Santa Anita officials announced on Sunday afternoon that there will be no training on the main track on Monday after 9 a.m. and none on Tuesday to allow officials to inspect the base.

Tim Ritvo, the chief operating officer at Santa Anita, described the inspection as a "precaution." He said the inspection will focus on ensuring the base has retained its integrity despite recent rains, which have been above normal.

Initially, officials said the track would not be open at all on Monday, but relaxed that position after an outcry from trainers who had planned workouts. Instagrand, the undefeated 3-year-old who is a candidate for the Grade 2 San Felipe Stakes on March 9, is scheduled to work on Monday morning.

The inspection comes after a weekend in which three horses were euthanized from injuries sustained in racing or training, notably Battle of Midway, the winner of the Breeders' Cup Dirt Mile at Del Mar in 2017. Battle of Midway suffered a fatal injury to a rear leg in a workout on Saturday morning.
