Green suffered an Achilles injury that kept him out of the game for a year. In his time out the team Blackpool won promotion back to the top flight. His return to the fold came on 19 September 1970 for the visit of Everton to Bloomfield Road. His profile increased that season when he scored both goals in a 4–0 home televised FA Cup third round win against West Ham United. The first was a solo run into the penalty and the second was a left foot drive into high into the net from just outside the penalty area. Blackpool were relegated at the end of that season back in the top tier. In their last league game of the season Green scored in the 1–1 draw against Manchester United.
