From Brisnet on March 24th....

"Trainer Mark Casse was upbeat Sunday about the Kentucky Derby (G1) status of Saturday’s beaten Louisiana Derby (G2) favorite War of Will, who never factored after taking a few awkward strides in the initial stages.

The 4-5 choice following victories in the first two Fair Grounds preps, the Lecomte (G3) and Risen Star (G2), War of Will had his hind end slip underneath him as he was trying to propel forward. His usual speed was nowhere to be found in consequence, and he wound up a distant ninth, by far the worst loss of his career.

Reporting that War of Will was “significantly off” Saturday evening, Casse surmised that it was likely a muscle strain. At that time it was premature to comment on his Kentucky Derby hopes."

Look at the video of the Louisiana Derby - around 10 seconds in War of Will (#6 horse) "loses his hind end" right after the start.
