Former Chargers and Chiefs cornerback Brandon Flowers is visiting the Cardinals on Wednesday, a league source tells Adam Schefter of ESPN.com (on Twitter). Flowers has also been talking with the Patriots, Schefter adds. 
Flowers was released by the Chargers just prior to the start of free agency. The Steelers expressed some interest in Flowers that week, but this is the first time that we’ve heard of other teams reaching out.
Flowers parlayed a strong 2014 season into a lucrative four-year deal with the Chargers before the 2015 season. He was unable to repeat that success in his first year with San Diego and his 2016 season was marred by concussion issues. Assuming that he is clear of any symptoms of brain trauma, he could be a valuable addition for teams in need of secondary help.
The Cardinals are presently without an established option to start at right cornerback opposite star Patrick Peterson. Justin Bethel and Brandon Williams have been battling it out for the job, but it’s possible that Bruce Arians is underwhelmed by what he’s seen so far this summer.
The Patriots have a lethal 1-2 combo of Malcolm Butler and Stephon Gilmore at cornerback, but they’re always on the lookout for additional depth. Eric Rowe, Justin Coleman, Cyrus Jones, and Jonathan Jones are among the other cornerbacks on the 90-man roster.
