Arizona Cardinals safety Tyrann Mathieu suffered a partially separated shoulder in Sunday's loss to the Carolina Panthers, according to Ian Rapoport of NFL Network.

Mathieu will undergo further testing Monday, but due to the Cardinals' upcoming bye, he may not miss any time with a Week 10 return possible.

It's decent news for Mathieu who has worked his way back from a torn ACL suffered at the end of the 2015 season.

Mathieu has been as active as ever in his unique role as the Cardinals slot-cover safety, tallying 27 tackles, an interception, and a forced fumble in eight games.
