Vannett (back) was a limited participant at Wednesday's practice, John Boyle of the Seahawks' official site reports.
After receiving treatment for the back issue during the Seahawks' Week 7 bye, Vannett is kicking off the current week in a positive manner. He'll look to build upon Wednesday's limited showing as the week continues with an eye toward returning Sunday in Detroit. He could be joined by veteran tight end Ed Dickson (quadriceps), who is practicing with the intent of coming off the reserve/non-football injury list.
