Stuart Broad admits there is no guarantee he can stay fit for purpose throughout five back-to-back Investec Tests against India.
He anticipates a physical drain on the collective resources of England's seam attack over the next six weeks, and acknowledges something might have to give for someone between Trent Bridge tomorrow and The Oval in mid-August.
Broad knows too, though, that he can improve his own chances of staying the course by doing what he is paid for – taking wickets, and shortening matches.
Chronic tendonitis in his knee has already curtailed Broad's season – he missed the limited-overs leg of Sri Lanka's tour – and, alongside his fellow pace linchpin James Anderson, he is an asset England's management are well aware they must protect.
Asked as he prepares for the first Test if he is confident he can get through all five matches, Broad said: "It's really hard to predict because if India go and get 400-500 every innings, then I wouldn't expect the seam bowlers to keep backing it up and playing.
"If we bowl India out for 250-300 every innings, it's obviously a huge difference on the workload."
The exacting schedule is a mixed blessing as far as Broad is concerned – an opportunity to get stuck into a long series, but with its physical effects in the back of his mind.
"It is important to have fresh bowlers in the side, and back-to-back Test cricket does really tire you out," he said. "This schedule's got five Test matches in the space of three, so it is pretty hectic.
"We will have to look after our bodies big time."
