By Tom Primmer The race to the Hospital Cup finals is beginning to heat up, as the season reaches its halfway point this weekend.  Title contenders GPS will host Brothers in a huge clash between two historical rivals at Yoku Road, with both sides looking to consolidate their positions in the top half of the ladder. After narrowly defeating Wests last weekend, the Gallopers have made just one change to their XV with Sam Curran moving into the starting side at lock.  GPS’ Matt Gicquel will go head-to-head with Reds and Wallaby flanker Fraser McReight at the breakdown, with McReight’s inclusion a huge bonus for the Brethren.  Jeeps head coach Shane Arnold emphasised the rivalry between the two great clubs as they prepare to do battle once again this Saturday, with Ashgrove playing host to GPS’ annual Old Boys Day celebrations.  “The GPS Brothers rivalry goes back generations and the old boys at the club see this as the biggest game of the year,” Arnold said
