Lotulelei (personal) rejoined the team Wednesday, Joe Buscaglia of The Athletic reports.
Lotulelei missed Sunday's win over the Patriots due to a personal reason but will likely be back in action for Sunday's Week 17 matchup against Atlanta. Assuming he's available, the 32-year-old should reclaim his starting role on the Bills' defensive line, though Harrison Phillips has started to play quite well recently during Lotulelei's frequent absences.
