Ryder hospitalised as NZ battle mounting casualty list

New Zealand batsmen Jesse Ryder was admitted to a London hospital after missing his team's Twenty20 World Cup loss to South Africa in England, New Zealand Cricket said in a statement on Wednesday.

Ryder was forced to pull Tuesday's game against South Africa at Lord's, because of a groin muscle injury and team officials later took him to hospital because of ongoing pain after the one-run loss.

"Jesse is continuing to suffer serious discomfort and has been admitted to hospital overnight for observation and further tests," team manager Dave Currie said in the statement.

"We hope the picture will become clearer in the next 24 hours."

Currie said New Zealand captain Daniel Vettori was receiving treatment to a shoulder injury that had forced him out of New Zealand's two matches so far.

Ross Taylor was being monitored after straining his hamstring while batting but left-arm paceman James Franklin was expected to play in the next stage despite a knee problem.
