Samuel (groin) was a limited practice participant Wednesday, John Keim of ESPN.com reports.
Samuel took two touches for 13 yards in Monday's 17-15 win over Seattle, playing 20 snaps on offense (24 percent) in his first appearance since Week 5. Assuming he's not dealing with any setbacks coming out of that contest, he could have larger role this Sunday in Las Vegas, though it's possible he'll remain a part-time player all year while managing the lingering groin injury.
