CUP: Rain Delays Michigan Green Flag

Morning rain has delayed the start of Sunday’s Quicken Loans 400 Sprint Cup race at Michigan International Speedway.

Heavy rain pounded the speedway area Sunday morning, but track drying has begun at the two-mile facility, and expectations are that the race will begin no later than mid-afternoon. Driver introductions have been rescheduled for 2 p.m. (ET).

The weather adds another wrinkle to an already difficult weekend at MIS. Track conditions will change significantly because of the precipitation on the surface.

Teams also will be wrestling with a late-arriving new left-side tire and the highest speeds ever recorded on a NASCAR non-restrictor-plate track.

Practice speeds approached 205 miles per hour, and Marcos Ambrose won the pole Saturday at 203.241.
