Lamb (triceps) was a full practice participant Wednesday, David Helman of the Cowboys' official site reports.
Lamb departed the Cowboys' Week 10 win against the Falcons with what was termed a bruised arm at the time. He still finished with six catches (on seven targets) for 94 yards and two touchdowns, despite logging a season-low 43 percent of snaps. On Monday, Mike McCarthy told Michael Gehlken of The Dallas Morning News that the second-year wide receiver "is going to be fine," and Lamb indeed has upheld his coach's optimism. Lamb thus will prepare himself for Sunday's road contest against a Chiefs defense that has given up 8.5 yards per target to wide receivers this season (11th-most in the NFL).
