Update: Coach Chan Gailey stated Monday that Jackson (head) will not play Thursday against the Dolphins, the Bills' official site reports. Gailey later indicated that Jackson did indeed suffer a concussion Sunday at New England in the fourth quarter.
Recommendation: As a result, look for C.J. Spiller to see added touches Thursday, with Tashard Choice in line for backup carries. Beyond that, Jackson's Week 12 status is unclear, but his chances of playing this week were obviously hampered by the Bills' short week.
