Moreau (abdomen/thigh) was listed as a limited participant in Wednesday's walkthrough, Rachel Gossen of the Raiders' official site reports.
Moreau was on the field for all 69 of the Raiders' snaps on offense in Monday's win over the Browns, so his listed limitations Wednesday could simply be a case of the team acknowledging that he came out of a busy Week 15 with some aches and pains. Meanwhile, Darren Waller (knee/back) logged a 'DNP' Wednesday, so provided Moreau's injury issues aren't a big concern, there's a decent chance he could head the Raiders' tight end corps again Sunday against the Broncos.
