MotoGP: Marc Marquez the star of Czech GP practice

Marc Marquez appears to be in the mood for providing entertainment after a wildly mixed bag of a practice day at the Czech Grand Prix.

The MotoGP championship leader was almost wiped out as he careered around turn 13, but the Spaniard managed to somehow keep his balance before coolly heading straight for the pits to regain his composure.

Once back on form, Repsol Honda's Marquez put in an impressive time of one minute 55.840 seconds to top the FP2 timesheets ahead of Ducati's Andrea Iannone, who had gone quickest in FP1.

The racy efforts in the second session suggest Marquez is back to full fitness after finishing fifth last time out in Austria, seemingly still hampered by a dislocated shoulder.

Ianonne grabbed his first MotoGP race win at the Red Bull Ring, Ducati's first victory in almost six years, and the rejuvenated Italian squad once again look set for an impressive outing.

Three of the top five times in FP1 were Ducati-powered, with Iannone's team-mate Andrea Dovizioso and Hector Barbera – out to impress after a bizarre disqualification in Austria – among the frontrunners.

Last year's winner in Brno and reigning riders' world champion Jorge Lorenzo was third fastest in each session, topping the timesheets each time before others overhauled him late on.
