ALLEN PARK, Mich. (AP) _ The Detroit Lions placed wide receiver Scotty Anderson on the injured reserve list Monday.

Anderson, who leads the Lions with 325 yards receiving, sustained a high ankle sprain in Sunday's 35-14 loss in Seattle, and was undergoing tests to determine if he would need surgery.

Lions coach Steve Mariucci said it was a ``strong possibility'' rookie wide receiver David Kircus would be activated off the practice squad. The sixth-round draft pick had a record-setting career at Division II Grand Valley State.
