There are three grades of turf toe injury. Grade one has a short 2-3 week turnaround. Grade two is 4-6 weeks. Neither of these require surgery. Grade three requires surgery and is the one that can end a season unless is occurs early. The latter is what Penning had and he's supposed getting close to being able to begin practice.

If Thomas had anything more severe than grade two he would have been placed on IR. I'd be shocked if he doesn't return within the next couple of weeks.
