Anderson -- who will miss practice Wednesday -- is getting a second opinion on his right knee injury, 9news.com reports.
The report notes that while there is hope Anderson's injury could be minor, the possibility that the running back could miss extended time has not been ruled out at this stage. Anderson's status for Sunday's game against the Chargers is thus cloudy, and if he is limited this week, or out, Devontae Booker -- who carried 17 times for 83 yards Monday night against the Texans -- would be in line for an expanded role.
