Looking over the GP assignments, there seem to be a few question marks about whether or not they're ready for competition since they haven't competed, even domestically, yet, so we might have a few withdrawals coming up. I'm deliberately not including skaters/teams whose status is known, information about is very limited, or they haven't been entered/withdrawn from any Challengers (Chock/Bates, Gilles/Poirier, Carreira/Ponomarenko, Wang/Liu, Muramoto/Takahashi, Knierim/Frazier, Crafoord/Crafoord, Peng/Jin, Zhu, Jin)
Men -
Kagiyama (SkAm & GPdF) - ankle injury caused him to withdraw from the Japan Open this weekend
Aymoz (GPdF & Espoo) - ankle injury at French Masters competition this weekend (my guess is he would be replaced by Landry le May at GPdF as a host pick)
Hiwatashi (MKJW & NHK) - unspecified injury caused him to withdraw from Lombardia Trophy 3 weeks ago
Zandron (NHK) - has not competed yet this fall, not even at the Austrian domestic Lentia Cup competition this weekend
Women -
Tennell (MKJW & Espoo) - ankle injury caused her to withdraw from Japan Open this weekend
Daleman (SCI & MKJW) - car accident & various other nagging injuries have kept her out of competition this summer/fall (no Canadian woman to replace her as a host pick since Lia Pereira had a JGP assignment earlier this season)
Yun (SkAm) - withdrew from Nebelhorn prior to FS due to warm-up accident where she was showing concussion symptoms
Peltonen (Espoo) - has not competed yet this fall, withdrawn from Budapest Trophy original entries list (would be replaced by a Finnish host pick - Janna Jyrkinen or Oona Ounasvuori)
Saarinen (Espoo) - has not competed yet this fall, not entered in any Challengers yet (would be replaced by a Finnish host pick - Janna Jyrkinen or Oona Ounasvuori)
Pairs -
Miura/Kihara (SCI & NHK) - she is in recovery mode from an ankle injury sustained in July while on tour, only resumed training throws about 2 weeks ago (probably replaced by Yunoki/Ichihashi as a host pick for NHK if they have to withdraw)
Safina/Berulava (GPdF & Espoo) - have not competed this fall, withdrawn from Finlandia original entries list
McBeath/Bartholomay (SCI & MKJW) - have not competed since they debuted their SP at a summer domestic comp, withdrawn from Nebelhorn original entries list
Faula/Belle (GPdF host pick) - barely cracked 106 total score at French Masters competition this weekend (no viable host pick option as Keriven/Bouvart scored even lower)
Dance -
Kazakova/Reviya (GPdF & MKJW) - have not competed this fall, withdrawn from Finlandia original entries list
Janse van Rensburg/Steffan (SkAm) - have not competed this fall, withdrawn from Nebelhorn due to slow recovery from unspecified injury
