Dale Steyn's long, long record-watch
A timeline of the injury troubles that have kept South Africa waiting to see if they have a new No. 1 in their ranks
Dale Steyn takes his 400th wicket in Bangladesh when he dismisses Tamim Iqbal on the opening morning of the second Test. Though Steyn takes two more wickets, there is no play possible on the remaining four days.
Steyn goes wicket-less for only the second time in his career as India are bowled out for 201 in their first innings in Mohali. He is unable to take the field in the second innings after sustaining a groin injury, which rules him out of the rest of the series.
A fit-again Steyn storms back at Kingsmead, dismisses Alastair Cook and Alex Hales inside the first seven overs and finishes England's innings with 4 for 70. But in the second innings, with South Africa well behind the game, he manages just 3.5 overs before leaving the field with a shoulder problem that sidelines him for eight months.
At the same ground he last appeared, Steyn takes two wickets against New Zealand in Durban in a low-key match where a wet outfield forces a draw under sunny skies. In the second match, Steyn shows shades of his best with eight wickets at Supersport Park to begin South Africa's resurgence from No.7 on the rankings.
A fired-up Steyn talks about cutting off the head of the snake as South Africa attempt a third successive series win in Australia. His warning is to Steven Smith and David Warner but he only ends up dismissing one of them, Warner, in Perth, just as things were getting away from South Africa. Steyn is so pumped up that he cranks up his pace and then goes down, clutching his right shoulder. The injury proves to be a rare break, the corricoid bone has snapped. Steyn has surgery, a pin inserted into his shoulder and spends 13 months in recovery, during which time he attempts several comebacks and tears a bicep and pec muscle.
Against all odds and much retirement speculation, Steyn returns for a marquee series against India. He takes a wicket in his third over and bowls 17.3 in the first innings. Then he lands awkwardly in a foothold and a muscle in his heel separates from the bone. He spends another six months on the sidelines.
Steyn signs for Hampshire in a bid to make an international return. In his first match, a fifty-over fixture, he concedes 80 runs in 10 overs. But he soon finds his rhythm and takes 5 for 66 in a County Championship game against Yorkshire and declares himself ready to try and break Pollock's record, in Sri Lanka.
