Marussia has confirmed that mechanical failure was not to blame for Timo Glock's accident in the second free practice session for the Chinese Grand Prix.

Glock went off into the barriers at the mid-way point of the session when an issue with the nose box on his car saw him skate across the gravel going into turn one, with the German reporting some pain in his hand at the time but escaping any injury as the steering wheel was yanked from his grasp.

After looking into the issue, the team has confirmed there was no mechanical failure which will allow it to now push on with its programme in the final practice session on Saturday morning.

"First and foremost we are obviously relieved that Timo seems to be fine," team boss John Booth said. "The next significant point is that we have clearly identified that the cause of the incident was not of a mechanical nature. This clarity enables us to push forward with our programme with confidence and continue to explore what, based on this morning's performance, seems to be a very positive step forward in aerodynamic terms.

"We have brought developments for the front wing, the rear brake drums and the floor here and the results shown in today's running leave us very optimistic about the direction we are moving in. It's frustrating therefore that we have found ourselves with the problem we encountered today but we can at least turn our thoughts to the rest of the weekend now. Charles [Pic] has played his part in an otherwise strong performance by the team today and he has once again come up to speed very quickly on his third consecutive unknown circuit. It will be a late night for sure but we look forward to a better end to tomorrow's programme."

Glock himself was pleased with the performance of his car despite the disappointing nature of the way his session ended.

"In general a positive day of progress with the car and I was happy with my pace and the way the car was working," he said. "Unfortunately we have experienced a problem which points towards an operational issue. While this is disappointing, we can at least be sure that this was not a car issue of any kind. In fact, the package, including the new developments, seems quite promising and I was happy with the good balance. There is damage to the car, as you might expect from the impact, but it is mainly cosmetic and the chassis is fine. A long night for the mechanics I think, so a frustrating outcome all round to an otherwise trouble-free day. Personally I am fine. Initially I had some pain in my hand from the steering wheel when I hit the wall but no lasting damage."
