It came out earlier this week that Arizona Cardinals cornerback Malcolm Butler was dealing with a personal issue and was mulling retirement. On cutdown Tuesday, the Cardinals placed Butler on the Reserve/Retired list, confirming the rumors.

Cardinals head coach Kliff Kingsbury said Tuesday the ultimate outcome with Butler “remains to be seen,” according to Darren Urban of the team's official website. Putting Butler on this list now saves a roster spot on the 53-man.

Arizona signed Butler to a one-year, $3.25 million contract in March, and the entire contract was guaranteed. The 31-year-old was released by the Tennessee Titans after he spent three seasons with the team.

Butler, of course, is known for being the hero of XLIX as a member of the New England Patriots. The cornerback picked off Russell Wilson at the goal line to seal the victory. He spent the first four seasons of his career with the Patriots and made the Pro Bowl in the 2015 season.

If this is in fact it for Malcolm Butler, the Cardinals could be in some trouble at the cornerback spot. Depth has been an issue at that position, so losing Butler would be a tough pill for Arizona to swallow after signing him in the offseason.
