Leyton Orient's midweek trip to Bradford City towards the end of February will now kick off at an earlier time.
Yianni hasn’t taken charge of Orient this season but has overseen Woking on one occasion, which was when they travelled to Macclesfield and ran out 1-3 winners in September 2017.
The Somerset born official has been in charge of 16 National League games, in which he has handed out 50 yellow cards, two red cards and four penalties this term.
