Cardinals S Mathieu, NT Ta'Amu out for start of training camp
JUL 23, 2014 4:12p ET
Considered a risky pick after his legal troubles at LSU, Mathieu rehabilitated his image with a superb rookie season after the Cardinals drafted him in the third round. Mathieu's season ended in early December when he tore two knee ligaments while returning a free kick against St. Louis.
Ta'Amu tore his ACL in a season-ending loss to San Francisco. No timetable has been set for their return.
Arizona also released receiver Kelsey Pope on Wednesday.
