Delayed Berit Milah

Tzitz Eliezer (Chelek 12 Siman 43) - explains that halacha is like the Shach that you can do a delayed berit milah on Thursday or Friday.

Rav Shlomo Zalman Auyerbach (Nishmat Adam OC Siman 331 Note 48) - also permits delayed milah on Thursday or Friday

Rav Masas (Shemesh uMagen YD Siman 45 Ot 6) - he also permits milah on Thursday bc today we are experts and the kid heals right away

Yabia Omer (Chelek 5 YD Siman 23) - says that a delayed berit milah should NOT be done on Thursday or Friday (unless they have an explicit minhag that permits it).

RBH agrees with Yabia Omer. Lechatchila never on Thursday or Friday. But, if they arleady invited for Thursday, can rely on the leninet opinions to not cause financial loss.
