Hoomanawanui will be placed on the Physically Unable to Perform list due to an undisclosed issue, Josh Katzenstein of The New Orleans Times-Picayune reports.
Head coach Sean Payton said he expects Hoomanawanui to resume practicing soon, so the injury doesn't seem to be a major concern. The 30-year-old tight end will compete for reps with veteran Ben Watson and Josh Hill once he returns to the field.
