The Browns worked out receiver Charles Johnson before the 2013 NFL Draft, but chose not to select him.
They eventually poached him from the Green Bay Packers practice squad last season only to discover the small-college standout had a torn anterior cruciate ligament.
The Browns finally are getting a look at Johnson on the field and general manager Ray Farmer finds him an "interesting prospect."
Johnson made several nice catches Sunday during practice. The 25-year-old is competing for a roster spot in a wide-open receivers field.
