Shaughnessy played 30 of 65 defensive snaps in his return to the field Sunday against the Chiefs, FOX Sports 910 Phoenix reports. However, he injured his shoulder in the fourth quarter, according to the Cardinals' official site, and was subsequently listed as limited in Monday's practice. Taking the field for the first time since Week 5, when he suffered a knee injury, Shaughnessy contributed three tackles, including two for loss. The lengthy absence from the lineup has delayed his first sack of the season, after racking up 18.5 in his first five years in the league, but with limited snaps perhaps on tap going forward, he may be blanked in the category for the first time in his career.
