Yah, 1-2 weeks. Given that the next two opponents are Bucs and and Pats, then Bills and Ravens, well, if he had to miss 2 games the former would be the two to miss.
It sounds like Higgins wanted to go but got vetoed by the coaches after his first play. That suggests he’s close, though you have to wonder if they keep him sidelined so he’s healthy for the last two games , too.
