Is There a Play On the UNDER Tonight CIN/LOU?

Is There a Play On the UNDER Tonight CIN/LOU? Bet the under 58.5 and 59 at Skybook, only to find out it's sitting at 55. Checked the weather and it's clear and in the mid 60's. So I figure this must be a play by some group. Bought some over 55's for a middle shot on part of the money.
Obviously late, but I but UN 58 this afternoon.
But why did it fall 3 points?
totals and lines for midweek games have been good fades of late. lang had big play on under...that was enough to get me on the over.

Glad I offset some overs
