On 20 January 2017, substitute Fletcher was one of three players sent off in a 2–1 loss at Brighton & Hove Albion, for headbutting Dale Stephens. He was punished with a three-match suspension. He scored both goals on 4 April as Wednesday won at neighbours Rotherham United, his first strikes since the previous December. Wednesday made the play-offs and Fletcher scored the goal that gave them the lead in the semi-final against fellow Yorkshire team Huddersfield Town, but was substituted before they lost on penalties.
