Moretti is highly doubtful to play. Apparently, he will not be ready to practice this spring. The recent OL puff piece did not even mention him. I think it is a fair guess his injury is not healed, and maybe even a reasonable assumption he is not going to ever play.
Moretti apparently is making progress (which was not necessarily the case when last season started), but I think realistically we are looking at a 2019 debut, if it happens at all.
