St. Louis signed Redden last week as an unrestricted free agent after he was extended an accelerated compliance buyout by the New York Rangers. Redden had been placed in the American Hockey League by the Rangers in order to keep his $6.5 million annual average salary off the team's salary cap.
In addition, Armstrong also announced that the club has assigned defenseman Ian Cole to the team's AHL affiliate in Peoria. It is believed that Cole was sent to the Rivermen in order open a spot for Redden.
The club also placed Jeff Woywitka on waivers on Wednesday. If he clears, he will be assigned to Peoria. Regardless of the outcome, Cole is expected to return to the Blues after Woywitka's status is determined.
