The Patriots designated Jacobs (concussion) for return from injured reserve Tuesday, Mike Reiss of ESPN.com reports.

EDGE Analysis

Jacobs was placed on injured reserve in mid-November due to the concussion he suffered in a Week 11 loss to the Rams. His practice participation this week will indicate his availability for Saturday's game against the Chargers. Jacobs has mostly played on special teams and has accumulated four tackles (two solo) across nine appearances on the season.
