Swaim (wrist) did not practice Thursday, Brandon George of The Dallas Morning News reports.
Swaim has missed the last four games after undergoing surgery for a fractured wrist in mid-November, and has yet to return to practice. The 25-year-old is trending towards remaining sidelined for Sunday's tilt against the Buccaneers, in which case Blake Jarwin would once again serve as the Cowboys' top tight end.
