Saturday’s 4-0 defeat at Portadown marked a performance described by Carrick boss Kieran Harding as “poor as we’ve been this season”.
Rangers now sit 10th in the Danske Bank Premiership standings after a return of four points from six fixtures.
Only Ballinamallard United and a Portadown side suffering from a 12-point Irish Football Association deduction sit below Carrick in the league table.
Rangers will attempt to build on the season’s sole league positive - a win away to Glentoran - with another road trip this weekend.
Carrick visit Coleraine Showgrounds on Saturday aiming to arrest a slump in form that has resulted in back-to-back league defeats, with four goals conceded to both Portadown and Ballymena United.
Those defeats arrived following a boost in form thanks to the Glentoran success away to The Oval and a draw at home to Ballinamallard United.
“We know we have a few to come back into the squad from injury,” said Harding. “But we need to get it sorted quickly otherwise we will find ourselves in real trouble.
“We were second-best to everything from start to finish.”
