The Cleveland Browns officially placed quarterback Brian Hoyer on injured reserve on Saturday.
To fill Hoyer's spot on the roster, the team signed rookie wide receiver Charles Johnson from the Green Bay Packers' practice squad.
Hoyer tore an ACL in his right knee Oct. 3 against the Buffalo Bills. He was replaced by Brandon Weeden, who will start Sunday against the Detroit Lions.
Weeden and Jason Campbell are the only quarterbacks on the Browns' roster.
Johnson was a seventh-round pick of the Packers in this year's draft out of Grand Valley State. He was waived Aug. 31 and signed to their practice squad Sept. 2.
