Glenn Irwin sealed a spot in the British Superbikes Showdown with a ninth-place finish in the final race of the weekend at Silverstone.

The Carrick rider had earlier finished 13th in race two after being awarded victory in Saturday's opening race.

It left him sitting sixth in the standings, with the top eight set to compete in the Showdown over the final three meetings of the season.

Jason O'Halloran won race three after it had to be restarted.

Luke Stapleford crashed off his bike on lap 11, with oil on the track leading to red flags before the riders gathered again for a 15-lap race.

O'Halloran, who had earlier finished second to Tarran Mackenzie in race two, won the final race of the weekend ahead of fellow Yamaha rider Mackenzie in second and Ducati's Josh Brookes in third.

Irwin's brother Andrew, who dropped out of race two on lap 20 after a technical problem, finished the final race in 11th place to leave him 13th in the overall standings.

Glenn Irwin had been awarded victory on Saturday when red flags came out after Mackenzie and O'Halloran crashed out on the penultimate lap.

He will now take his place in the Showdown with a top eight in the standings that includes O'Halloran, MacKenzie, Tommy Bridewell, Christian Iddon, Peter Hickman, Irwin, Danny Buchan and Josh Brookes.

Bradley Ray and Lee Jackson just missed out on the Showdown, which will get underway at Oulton Park on 25 September.
