Skipper Grant Leadbitter struck for the second time in three games as 10-man Middlesbrough eased past Sheffield Wednesday 3-0 and into the FA Cup fourth round. Leadbitter’s 58th-minute free-kick finally ignited a previously dull encounter, although Boro defender Daniel Ayala was controversially dismissed for a professional foul on Fernando Forestieri within seconds to give Wednesday hope in front of a crowd of 23,661 at the Riverside Stadium.
