How long to defrost a 3.8kg boneless rolled turkey crown?

[BlackAmericanoNoSugar]

I want to cook it for dinner on Sunday. It was supposed to be cooked from fresh on Christmas day but we had something else instead, so the instructions are just about cooking and not about thawing.

Whole bird defrosting instructions here, maybe a tad longer as it’s rolled!

If there are no defrosting instructions, thaw your turkey in a fridge at 4C (39F) for 10 to 12 hours per kilogram. Be aware that not all fridges will be set to this temperature. When your turkey is fully defrosted, keep it in the fridge until you're ready to cook it

Thanks, I'll start it now.
