Once considered a rising coaching star, Donnie Henderson spent 2009 as a volunteer for the UFL franchise in California.
Brad Biggs of the NFP reports that Henderson is getting back into the NFL as the next defensive backs coach of the Cardinals, replacing Teryl Austin.
Henderson was a secondary coach for the Ravens from 2000-2003, then went on to rocky defensive coordinator gigs with the Jets and Lions. The Cardinals sent three defensive backs to the Pro Bowl in 2009, but one of them looks likely to be released soon.
UPDATE: The Cardinals have since officially announced the move.
