NFL Media Insider Ian Rapoport confirmed on Friday's edition of NFL Network's "Around the League Primetime" that Smith will indeed play, albeit in a limited role as a situational pass rusher to highlight his strengths.
Niners defensive coordinator Vic Fangio noted that Smith looked "a little rusty" in practice this week. As expected, Smith's conditioning is at less than peak form after missing six weeks for treatment at a rehab facility.
Rapoport also echoed an earlier report by NFL Media columnist Michael Silver that Smith will have to earn his full-time role back over the next few weeks. Rookie pass rusher Corey Lemonier has exceeded expectations while filling in for Smith over the past month.
