To fill the roster spot, the Browns signed rookie wide receiver Charles Johnson from the Packers’ practice squad.
Hoyer suffered a torn anterior cruciate ligament in his right knee in Cleveland’s victory against Buffalo on Oct. 3. He was replaced by Brandon Weeden, who will start Sunday against Detroit.
Weeden and backup Jason Campbell are the Browns’ lone quarterbacks on the roster.
A seventh-round pick from Grand Valley State, Johnson (6-2, 215) was waived by the Packers on August 31, then re-signed to the practice squad on September 2. Johnson racked up 1,199 receiving yards and scored 16 touchdowns as a senior in 2012.
