The Lions placed Moseley (pectoral) on injured reserve Tuesday and designated him to return.
Moseley tore his pec during a practice in early August and is expected to be sidelined for an extended period. Under a new NFL rule, the Lions were able to exclude him from the 53-man roster on cutdown day and place him on IR while designating him to return. As such, Moseley will be eligible to return after missing Detroit's first four games of the season.
