Steelers' Zach Frazier: Added to injury report

Frazier (triceps) did not practice Thursday, Brooke Pryor of ESPN.com reports.

Frazier wasn't listed on Wednesday's injury report, so his triceps issue appears to have occurred during practice. The starting center's presence will now need to be monitored ahead of Sunday's contest against Detroit. Frazier will have one more chance to get back on the practice field for Week 16 on Friday.
