Pval returns with a million dollar race win

Well hes done it again. No matter how many times he goes AWOL, when Pval returns he never ceases to amaze everyone. Guy picks up his first mount back off his most recent AWOL and gives an incredibly perfect ride and nails the Woodbine Mile.
What interested me were his comments after the race about his back and his workout program.
I know you can't believe anything he says but is it perhaps possible that his back really was killing him and that it was the problem?
