Miller, 22, wound up signing on with the Browns as an undrafted free agent out of Kentucky back in May. He was unfortunately among their final roster cuts coming out of the preseason, but was later added to their practice squad.
This season, Miller has been active for two games.
Johnson, 23, also signed on with the Browns as an undrafted free agent out Mississippi State a few days after this year’s NFL Draft. He managed to make the 53-man roster coming out of the preseason.
This year, Johnson has appeared in 12 games and ran for 15 yards on four carries (3.8 YPC) and no touchdowns.
