McNamara has kept faith with the halfback pairing of Kevin Sinfield and Rangi Chase. Chase will start against the team who he helped defeat England in last year’s International Origin match.
McNamara said: “Every training session and every game counts ahead of the World Cup, because there are not too many of them. We are quite fortunate to have two games against the Exiles and an end of season programme this year going into 2013, but every second does count when you are with the England group.
“We are coming into the final stretch of the season once we get this Exiles game out of the way, and it feels like only two minutes ago since the season started.
“The same will happen for the World Cup. Once we get the Exiles games out of the way and the end of season tournament, the 2013 season will be upon us. We need to be ready, and we will.”
