Loan deal to MLS club sounds like is gonna happen.
"Winston Reid is going to join a club in America on loan, everything being well," West Ham manager David Moyes said.
"I don't want to give you a club just now, he's got to get through a medical and a few other things."
Reid joined West Ham in 2010 after representing New Zealand at the World Cup in South Africa.
The Daily Mail reported that Sporting Kansas City and expansion side Nashville are both in the running to sign the 31-year-old centre-back.
FYI - from AWs perspective with the March FIFA window (23-31 March), Nashville don't play but Sporting KC do. Also out of interest both these MLS sides are in the Western Conference.
