In July 2017, Johnson signed with SC Telstar. In the beginning of 2018, Johnson received the message, that he wouldn't play anymore for the club. He was excluded from training by the club, because he no longer fitted into the plans of the club's head coach. Because the club didn't have a reserve team, this exclusion meant that Johnson actually had to sit at home. Johnson did not agree with this course and went to VVSC. After finding no solution, the case was presented to KNVB. The Commission considered the exclusion of Johnson as substantial. Johnson began training again, while Telstar was sentenced a penalty.
