STOKE promoter Dave Tattum admits his patience has worn thin with his under-achieving side following a huge 35-55 home defeat to Workington on Saturday.
The reverse came on the back of a 68-24 mauling in Cumbria the night before and was a sixth consecutive defeat for the Easy Rider Potters.
Tattum said: 'Something has to be done because the crowd were having a go at some of the riders - and understandably so.
'There will be options available to me and I will have to consider those options before doing anything. But something needs to change quickly because we are just not getting it together as a team.'
Stoke lost Jack Hargreaves with a back injury in Heat 2 of the defeat at Workington and had to draft in Simon Lambert for the home meeting on Saturday.
Garry Stead also suffered a bad crash at Workington and wrote a bike off as well as being battered and bruised, though he was able to ride on Saturday.
Stead blew two motors on Saturday, Rusty Harrison was another to struggle with his engines whilst Ben Barker and Paul Pickering also blew motors over the two meetings.
Stoke travel to Kings Lynn on Wednesday and then host the Norfolk outfit at Loomer Road on Saturday. Team boss John Adams said: 'We have to be realistic because Kings Lynn is always a hard place to go to. But we need to get points on the board and our home meeting next Saturday will be a big, big meeting for us.'
Stoke SAS Spitfires start their season on Friday when they travel to Boston in the Premier Trophy, while Ben Barker rides in the British U21 qualifying round at Weymouth on the same night.
