Australian all rounder Marcus Stoinis was run out after a bad mix-up with teammate Steve Smith left both batsman stranded at the same end during the ICC Cricket World Cup clash against England at Lords on Tuesday.
"Some days during all the rehab periods you think 'am I going to get back?'" Behrendorff said after Australia dismissed England for 221 in reply to their 285-7, to win by 64 runs.
England may now have to beat both in-form India and New Zealand in their final two pool matches if they are to keep alive their hopes of winning the World Cup for the first time.
"England are a standout side, they are a team that can take you apart at stages".
The total still proved too great for England, however, with Jason Behrendorff (5-44) - a maiden five-for in only his eighth ODI - and Mitchell Starc (4-43) making inroads in bowling that fuller, testing length that England failed to. "We were as tight as we could be and tried to cash in on the width", he said.
"Mitch and Pat have played a lot of one-day cricket". I don't think they did. He is a very good character and a very good man under pressure and he has been flawless at this hard time for Australian cricket.
Their problems, of course, began well before Tuesday and the loss of Jason Roy is proving to be a real blow because England have been used to getting off to flying starts.
James Vince was bowled second ball by a beauty from Behrendorff, swinging back in and beating him through the gate, while Joe Root (8) was undone by an nearly identical delivery from Starc which trapped him lbw. "But James Vince coming in, he is a phenomenal player".
The 28-year-old suffered a similar injury during England's tour of the Caribbean earlier this year and with the World Cup featuring a long pool phase that sees all 10 teams play each other ahead of the semi-finals, the 28-year-old Roy is confident of returning to action. As for the rest, Morgan might look at bringing in Liam Plunkett if they want to rest Mark Wood who was set to be rested for the game against Sri Lanka.
