Johnson (groin) does not have an injury designation for Sunday's Week 13 contest against San Francisco.
Johnson sat out last week's win over Buffalo due to a groin injury, but he was able to log two full practice sessions this week. As such, he'll be able to suit up in a key NFC clash against the 49ers on Sunday. Johnson's presence will be a big boost to Philadelphia's offensive line against a 49ers defense that ranks second in the NFL in fewest rush yards allowed and 11th in sacks on the season.
