Patriots TE Jonnu Smith sprained his left ankle in Sunday’s practice. ESPN’s Mike Reiss reports that it’s a low-ankle sprain. “No firm timetable on his return, but based on the initial diagnosis, it isn’t considered a serious injury,” Reiss says. We’ll see how long Smith sits. Hunter Henry, of course, is already out with a shoulder injury. So New England suddenly looks thin — for the moment — at TE. That means opportunity for a WR corps without much separation so far.
