Tampa Bay's walk-through injury estimate lists QB Baker Mayfield (right thumb), S Antoine Winfield Jr. (rib), CB Benjamin Morrison (quad) and LB SirVocea Dennis (ankle/foot) as did-not-participate; TE Ko Kieft (elbow) and LB Josiah Trotter (knee) were limited.

The undrafted rookie makes his second straight start in place of injured Baker Mayfield (thumb) in a national Thursday-night window against a Dallas team averaging roughly 31 points per game, with Tampa Bay's own scoring having fallen every week this season.

Winfield, a two-time Pro Bowler and 2023 All-Pro, fractured a rib in Sunday's loss to Green Bay; Ifeatu Melifonwu takes his role for the short-week game against Dallas.

Mayfield (thumb), Reuben Bain Jr., Ko Kieft and Benjamin Morrison were all ruled out, though Chris Godwin Jr. and Bucky Irving returned to full practice.

Mayfield dislocated his thumb and is expected to miss three to six weeks; Tampa Bay turns to Daniels while targeting a possible Week 7 return for its starter.

Tampa Bay's starting quarterback will miss the game after dislocating his thumb last week; an undrafted rookie is next in line.

Tampa Bay's already-thin roster loses three more starters as the winless club tries to avoid an 0-4 start at home.

Mayfield dislocated his throwing-hand thumb late in the loss to Minnesota; an MRI showed no fracture or ligament damage, but he's expected out a minimum of three weeks, with undrafted rookie Jalon Daniels taking over.

None of the four practiced all week; Tampa Bay also lists three more players as questionable ahead of Sunday's home game against Green Bay.

The undrafted rookie makes his first career start Sunday behind a line that has allowed the most sacks in the league this season.
