The LCR Honda rider was running behind Johann Zarco's Tech 3 Yamaha in sixth when he lost the front and crashed at Turn 20 on lap eight.

He remounted and went on to finish out of the points in 19th place.

Explaining the incident, Crutchlow said he couldn't afford to spend anymore time behind Zarco as he was conscious of the bikes ahead getting away - and that he felt he had the pace to be second.

"I made a stupid mistake out the last corner," he admitted. "I was trying to square the bike to have a run at Johann into Turn 1, and as I leant at the last moment, I opened the throttle and closed the front.

"I'm not a sixth-place rider this year. So I'm not gonna settle for sixth. I was nowhere near a sixth-place rider today, I was fast enough to be second.

"I'm a racer and you need to understand when someone's in front of you, and they're going slower than you can go, I'm not gonna ride round behind them.

"I needed to clear Zarco and go, because they were not extending their gap ahead of me so I knew I could go across quite easily.

"We have to take the positives to Jerez, that we're fast enough. I think it will suit me better, even though we should have finished second but we didn't because it was my fault."

Crutchlow had led the championship coming into Austin following his race win in Argentina, but now lies equal fourth with Zarco, eight points behind new leader Andrea Dovizioso.

The Briton acknowledged that not being in the points lead would help him to focus on aiming for the podium at every race.

He said: "I'm not saying I don't want to be championship leader, but in a way maybe it's better not to be, because then you can focus on being on the podium week in, week out, which I think we can be, instead of focussing on what the team wants, to finish fifth or sixth, to rack up points.

"If you chase podiums, the championship will come. In Qatar I finished fourth, but I was chasing the podium. In Argentina I won, I knew I could win.

"Here I'm not saying I thought it was impossible to win, but I knew it would be difficult. I actually thought it would be easy to be on the podium, and it was."
