What happened: Jalon Daniels will start at quarterback for the 0-3 Tampa Bay Buccaneers with Baker Mayfield sidelined at least three weeks. The undrafted Kansas rookie becomes the first rookie quarterback to start a game this season, ahead of all 10 drafted quarterbacks.

Why it matters: Tampa Bay sits 0-3, leaving little margin as it turns to an undrafted rookie at the league's most important position. Daniels reaching a first start before the entire drafted quarterback class underscores how quickly the depth chart shifted after Mayfield's absence.

What to watch: Daniels' debut will show how Tampa Bay adjusts its offense without Mayfield. His play over the next three weeks will shape the quarterback rotation when Mayfield is eligible to return.
