Struggling with last few:
1a "Contact sport Islamic judge holds undesirable" (7)
K?B?D?I The undesirable is presumably BAD but I can't find the name of an Islamic judge to go outside it and give the name of a contact sport.
23d "Use up time over video which may be launched by club" (5)
D?V?T I presume it's DIVOT which would give something launched by a golf club but can't parse it,
Any help much appreciated
