Nwosu (thigh) was a full participant in Wednesday's practice, John Boyle of the Seahawks' official site reports.
Nwosu looked on track to return from injured reserve for this past Sunday's win over the Jets after logging a full practice Friday, but the Seahawks ultimately took a cautious approach with him and didn't activate him from IR. If Nwosu is able to continue to string together full practices this week, he should have a better chance at playing this Sunday at Arizona.
