MotoGP: Dani Pedrosa to evaluate injured ankle on Saturday morning

In the opening minutes of the second Brno session, Pedrosa crashed on fluid from his own Honda at Turn 14, landing heavily on his left foot.

Investigation from the team found oil leaking from his front fork as the culprit.

Pedrosa didn't run again during the 45-minute session, electing to ice the ankle in the Honda transporter.

While x-rays didn't show a break or fracture, Pedrosa acknowledges that how the heavy bruising settles overnight will be vital.

"I had a problem with the front fork which I didn't realise until some oil hit the rear wheel as I was leaning over to the right into Turn 14," the reigning Brno winner said.

"The bike threw me off quite violently and I took a big knock to my left foot.

"I went to Clinica Mobile for a check-up and they performed an x-ray on my left ankle.

"Thankfully they confirmed there was no break or fracture, just a heavy contusion so I will have some treatment tonight and see how the situation is in the morning."

Team-mate Marc Marquez topped the incident-packed session, despite a late crash of his own, following an off in first practice.

He was second-fastest for the day, behind Yamaha's Jorge Lorenzo, who set his time in the cooler morning session.

"Today was a very productive day, we have obtained a lot of data and we have seen that this will not be an easy circuit," Marquez said.

"I am fast over a single lap, but I am finding it harder to set a constant pace.

"In FP2 we finished first, but more importantly we have made a step forward with our pace, because it seems that Lorenzo is has a very fast rhythm.

"This afternoon we got close to him and we will see if tomorrow we can continue to improve, in order to be as close as possible to the top."
