Colin Pascoe and Mike Marsh will deputise for manager Brendan Rodgers in the technical area at Loftus Road today, after three members of the travelling party were struck down with illness.
The Reds boss has been sent home from London ahead of the Barclays Premier League game against QPR on doctor's orders after succumbing to a likely virus that has made it impossible for him to be in close proximity with the players.
Glen Driscoll, LFC's head of performance, and goalkeeper Brad Jones have also been sent home by the club's medical team.
Club doctor Zaf Iqbal said: "It was impossible for Brendan, Glen and Brad to attend the game. They are not fit to be at the match and any contact with the rest of the squad could cause the bug to spread to more of the playing staff."
