Bryan Staring was frustrated by a shoulder injury which slowed his progress in the second-half of the grand prix.

A niggling shoulder injury has prevented GO&FUN Gresini Honda’s Bryan Staring from making the desired progress in the Indianapolis Grand Prix, with the Aussie describing the 27-lap race as “pretty average”.

The result is a disappointing end to a promising Brickyard campaign for Staring, who developed an instant liking for the track and had been making good progress in the free practice sessions.

He qualified his Honda in position 20, making a solid start from the seventh row of the grid, but as the race wore on the level of physical exertion began to take its toll.

“After yesterday’s performance, and from Friday onwards, we were improving and working quite well and I was confident we had a really good package for the race,” said Staring.

“But it didn’t come together. Basically the biggest problem was I’ve had a bit of a weak shoulder. It’s a crap excuse but I really couldn’t push after half race.”

The Australian is hopeful of putting in a competitive performance at Brno this weekend, with the championship moving directly to the Czech Republic for the 11th grand prix of the season.

“It seems to be much less of a problem on the circuits that go right,” he added. “I’ve had this problem all year, but it’s been quite acceptable, so I don’t know why it’s popped up again now.

“We tried every possible way to improve our confidence but didn’t manage it and I am sorry to the team.”

He was the final classified finisher of the Indianapolis Grand Prix, finishing one lap down as the chequered flag was waved.
