Cardinals tight end Troy Niklas (hamstring) was a full participant at Wednesday's practice, FOX Sports 910 Phoenix reports.
In Sunday's regular season opener, Niklas was a distance third in terms of tight-end snaps, earning three to Jermaine Gresham's 24 and Darren Fells' 52 (among 62 for the offense).
Due to the lack of reps, it was no surprise that Niklas wasn't even targeted. In any case, the rare full showing in drills bodes well for active status yet again Sunday at Chicago, but he'll likely remain third in the TE pecking order.
