I think he remains on the rising star list until it is revised.
Note: this is an opinion based on the impression I have gained, I am not in the least bit certain that this is indeed the case. I refer you to geoff100's comment
10.2.1 A Premiership or Championship Assessed League rider will establish an MA after 4 home and 4 away fixtures. Becoming effective 7 days after the last
qualifying meeting.
Thompson's average is therefore most definitely 6.05 today - typo on greensheets notwithstanding)
However I think Thompson remains a 2* Rising star and can therefore guest for Jenkins under:
012.4 Facilities – page 113
D) Absent 6 th rider by MA – Guest. D1) Absent Rising Star – Same star rider or lower.
Currently Dan Bewley, Dan King, Adam Ellis and Rory Schlein are the best options. (I suspect Bewley's average will not stay below Ulrich's for much longer)
Not British, but
Anton Jansson who competed in the FIM Youth Gold Trophy last weekend is a fourth generation rider.
Father Jimmy
Grandpa Bo (and great uncle Tommy)
Great grand father Joel
With both the DSL and the Allsvenskan riding on Wednesday's that may be a bit limiting ( although Pollestad, Sola and Fredriksen might offer some interesting Norwegian options)
I'm generally sceptical of how much value a TM can add to a team's performance, but in many ways Mr Dickson was very much the Lions match winner yesterday.
That's a great encapsulation of British league speedway. However with a few exceptions ( e.g. BL2/NL in the 70s) that's pretty much been the state for over 50 years
