Bridgewater, 26, agreed to a one-year $7.5 million deal that is worth up to $12.5 million with incentives, sources told ESPN's Adam Schefter.
Miami intends to draft a future franchise quarterback in the 2019 or 2020 National Football League drafts, and hopes Bridgewater could bridge the gap.
Rumors of Teddy Bridgewater's signing with the Saints may have been greatly exaggerated. He's expected to once again back up 40-year-old Drew Brees. Bridgewater looked to be in line to land the starting job in New Orleans after Brees' retirement, but it looks like he's considering other options.

In Lagos that same year, a five-story building still under construction collapsed, killing at least 30 people. Associated Press video from the scene showed a dust-covered child being carried out of the rubble, to cheers.
The Dolphins will likely release Tannehill with a June 1 designation in order to save $18.75 million in salary-cap space.
That may not have been the case had Bridgewater signed in Miami. He went 17-11 in two seasons as the Minnesota Vikings' starter before a broken leg changed the course of his career. He looked great with the Jets in preseason past year and the Saints were willing to give up a third-round pick for Bridgewater.
Bridgewater, who was an unrestricted free agent, was expected to re-sign with the New Orleans Saints after declining Miami's offer on Tuesday.
