Reports of a four-game suspension of cornerback Walter Thurmond cause concern over depth at a position already weakened by the groin injury to starter Brandon Browner.
ESPN's Adam Schefter reported the violation is of the league's policy for non-PED substances. Thurmond's four-year career had been sidetracked by a series of leg injuries. With Browner on the sidelines, Thurmond had the first interception of his career last week against Minnesota.
Cornerbacks Byron Maxwell and Jeremy Lane have seen action as substitutes at cornerback this season. DeShawn Shead is the lone cornerback on the practice squad.
The Hawks have this week off and return to action in an important NFC game Dec. 2 against New Orleans, the No. 2-ranked passing team in the NFL.
Thurmond got his lone start last season when Browner was serving a four-game suspension for a bad PED test.
