Swaim isn't expected to play in Thursday's preseason matchup with Philadelphia due to an undisclosed injury, John Oehser of the Jaguars' official site reports.
It's unclear how serious Swaim's injury is, although head coach Doug Marrone could just be exercising caution with the 25-year-old. When healthy, Swaim figures is the Jaguars' projected starter at tight end.
