Mathieu, 23, is a former third-round pick of the Cardinals back in 2013, who has quickly become an impact player for one of the best defensive units in the NFL.
Mathieu has two years remaining on his four-year, $3.052 million rookie contract that included $817,187 guaranteed. He’ll make a base salary of $585,000 this season and another $675,000 in 2016.
In 2015, Mathieu appeared in 14 games and recorded 89 tackles, a sack, five interceptions with one being returned for a touchdown, a forced fumble and 16 pass defenses for the Cardinals. Pro Football Focus has him rated as the No. 1 cornerback out of 111 qualifying players.
Clemons, 30, is a former fifth-round pick of the Dolphins back in 2009. After five years in Miami, Clemons signed on with the Texans as an unrestricted free agent in March of last year.
The Cardinals elected to sign him to a two year, $2.7 million contract this past March, but wound up being placed on the injured reserve list and later being released with a settlement.
This year, Clemons has appeared in five games and recorded three tackles for Arizona.
