Harris (Achilles) is inactive for Sunday's wild-card matchup against the Cowboys, Cam Inman of The San Jose Mercury News reports.

EDGE Analysis

Harris will be sidelined for the second straight week due to the Achilles injury. However, the good news for the 49ers is that fellow weakside linebacker Azeez Al-Shaair (knee) will be available, so they won't have to start their third stringers against the Cowboys' high-powered offense.
