Swaim is expected to undergo surgery on a torn pectoral muscle at some point this week, Brandon George of The Dallas Morning News reports.
Swaim did not hold much stock as Jason Witten's backup but provided blocking assistance for the team's highly effective ground game in two-tight end sets. A return this season is seemingly doubtful given that surgery is imminent. Gavin Escobar is in line to fill in as the team's backup tight end.
