Hey there Fable, this is a pretty huge problem, sometimes the whole cola can atrophy and die . sometimes the plant survives it though, and the cola lives. I wouldnt cut it off until your very much have to, my main worry is if the roots have a problem, but it doesnt look like it . Keep monitoring it if it gets worse and dies you should remove it , until then help the soil with some humic acid and it could help reduce stress and shock. Hope this helps ! 🚀
