JP Du­miny has been ruled out of South Africa's World T20 match against West In­dies on Fri­day af­ter sus­tain­ing a ham­string strain in their game against Afghanistan.

The ex­act length for his re­cov­ery is un­known but South Africa are hope­ful of hav­ing him ready for their fi­nal group game against Sri Lan­ka on Mon­day.He sus­tained the in­jury when he chased the third ball of Afghanistan's in­nings and left the field be­fore the open­ing over was com­plet­ed.

"He was chas­ing the ball full steam and re­alised he was too close to the bound­ary and tried to stop him­self. These things hap­pen," Mo­ham­mad Moosajee, South Africa's team man­ag­er, said al­though he did not sound over­ly op­ti­mistic about Du­miny's prospects of re­cov­ery.

"Bran­don Jack­son, our physio, will have his work cut out for him. With these things you can't re­al­ly put down a time frame. It could be any­thing from sev­en to 14 days. We know in the past there were guys that re­cov­ered ear­li­er than ex­pect­ed and guys that just didn't. It's very much a wait and see and see how he re­sponds. It's very im­por­tant that he goes through the re­turn to play pro­to­cols and pass­es a fit­ness test to be con­sid­ered for se­lec­tion."

When asked if there are thoughts of re­plac­ing Du­miny in the squad, Moosajee dis­missed those. "It's still very pre­ma­ture," he said.

Du­miny's ab­sence will leave South Africa with a se­lec­tion co­nun­drum ahead of the West In­dies meet­ing. Nag­pur's sur­face will de­mand more than one slow­er-bowl­ing op­tion–New Zealand played three spin­ners there to beat In­dia–and Du­miny could have pro­vid­ed that. So far, South Africa have on­ly field­ed one spe­cial­ist spin­ner in Im­ran Tahir but are like­ly to al­so look to the oth­er spin­ner in their squad Aaron Phangiso against West In­dies.

Phangiso has not played an in­ter­na­tion­al match since Oc­to­ber last year and has re­cent­ly had to re­mod­el his ac­tion af­ter it re­port­ed in do­mes­tic crick­et dur­ing Feb­ru­ary. The on­ly crick­et Phangiso has played with his new ac­tion was in the two warm-up match­es in In­dia, in which he bowled a to­tal of four overs.

Phangiso's in­clu­sion will al­so short­en South Africa's bat­ting line-up which could force an­oth­er change. One of the all­rounders, Chris Mor­ris or David Wiese, may have to make way for ei­ther Rilee Rossouw or Farhaan Be­har­di­en, both of whom can al­so bowl a bit. (Cricin­fo).
