Rawls missed Thursday's practice due to an illness, John Boyle of the Seahawks' official site reports.
After enduring a lengthy recovery from a broken ankle, Rawls finally shed his injury designation Wednesday for the first time since Week 14 of last season. Seemingly in line for as much work as he could handle Sunday against the Dolphins, according to head coach Pete Carroll, Rawls may have hit another bump in the road. If the malady lingers into the weekend, Christine Michael could be more of a No. 1 back than expected.
