What happened: Dobbs' one-year contract is worth $1.425 million with $475,000 fully guaranteed. Keanaaina joined Detroit as an undrafted free agent in May after the 2026 NFL Draft.
Why it matters: Dobbs restores veteran quarterback depth after Detroit placed Teddy Bridgewater on the reserve/retired list Sunday. Keanaaina's move trims one rookie from the defensive-line competition during preseason roster construction.
By the numbers: Keanaaina played 36 college games across six seasons, totaling 112 tackles, 6.5 tackles for loss and 3.5 sacks.
What to watch: Watch how Detroit divides its preseason quarterback reps and adjusts the defensive-line rotation.
