What happened: The Dallas Cowboys activated Pro Bowl left guard Tyler Smith from injured reserve ahead of Thursday's game against the Tampa Bay Buccaneers. He makes his season debut after undergoing thumb surgery shortly before the campaign began.

Why it matters: Smith's presence immediately reinforces the interior of the Dallas offensive line. Reintegrating one of the league's premier blockers solidifies their protection schemes against a strong Tampa Bay defensive front.

What to watch: Monitor how Smith's thumb holds up during his first live game action of the year. His effectiveness in the trenches will be a major factor in the matchup.
