Jockey Mary Jo Brennan suffered several broken ribs, a partially collapsed lung and multiple bruises in a spill during yesterday's fifth race at Philadelphia Park.

Brennan, 42, was aboard Love Walk, who broke down and fell in the stretch, apparently rolling over the fallen rider.

The jockey was admitted to Frankford Hospital-Torresdale Campus and was under observation in the intensive care unit last night.

Love Walk, a 4-year-old filly, was euthanized.
