AP source: Cardinals, Mathieu agree to 5-year, $62.5M deal (Yahoo Sports)

A person with knowledge of the situation tells The Associated Press that the Arizona Cardinals and All-Pro defensive back Tyrann Mathieu have agreed to a five-year, $62.5 million contract extension, with $40 million guaranteed. The big contract comes despite Mathieu's major injuries to each knee in two of his first three NFL seasons. Mathieu was considered a risk when the Cardinals chose him in the third round (69th overall) in the 2013 draft but quickly developed into one of the team's top players and evolved into a vocal leader with no off-field issues.
