McAMS Yamaha duo Jason O'Halloran and Tarran Mackenzie were on a damage limitaton exercise at the Cadwell Park Bennetts British Superbike round as injury forced them both out of any realistic chance of big points scores.

Mackenzie rode with the broken wrist sustained at Thruxton while O'Halloran is still suffering with the shoulder he damaged at Snetterton which requires some further investigation.

Starting sixth in race one, O’Halloran vaulted off the line to sit third in the early stages before slowly dropping through the pack as he struggled to manoeuvre the bike through the circuit’s physical Hall Bends section.

Settling in to seventh, he maintained his rhythm to bring his YZF-R1 home. In race two, he’d get a similarly good start but found himself squeezed out at turn one as he looked to move into third. Running across the grass, he re-joined the circuit dead last, five seconds behind Shaun Winfield in front. Chipping away throughout the race, the Aussie crossed the line in 14th position.

"This morning I had to be happy, we got a good start and got away with the leaders and then I just had to manage the race. I could only ride the pace I could ride with my shoulder," said the Australian.

"The bike was feeling good and we picked up some points. In the second race we started on row three and I got another mega start, just like we have all year, but it was probably a little too good as I ended up on the outside in fourth and I got hit from the inside and punted off the track so the race was over at that point.

I stuck at it as you never know, a couple of points is a couple of points and the safety car could have come out. I managed to finish 14th. I've now got three weeks off, so I'm going to get my shoulder looked at as it should be better by now. Hopefully we can find out what the prognosis is and move on to Oulton Park."

There was a huge question mark over whether Mackenzie would ride on Sunday with the 23-year-old only having completed a maximum of five laps at a time across the weekend.

However, he gritted his teeth and completed 18 gruelling laps in the first race to cross the line 13th in the first race, before doing it all over again in race two and improving his position to 12th, claiming seven valuable points that could be hugely important come the Showdown decider at Oulton Park in three weeks’ time.

"The goal this weekend was to score at least one point so to get seven is good for me. Obviously I lost a few points to some of the people like Danny Buchan and Hickman but other than that I was happy with the weekend as I wasn't expecting to ride.

"Seven points could make the difference for the showdown come Oulton Park in three weeks' time. We'll leave here, get the wrist working normally and hopefully I can ride with two arms at Oulton Park."
