Norwich City head coach Johannes Hoff Thorup has revealed captain Shane Duffy was absent from their starting line-up in the 1-1 draw with Oxford because he missed a team meeting.
The 33-year-old was an unused substitute for the game at Carrow Road.
"Shane was late for the team meeting," Thorup told his post-match press conference.
"I set a culture for a football team and tell the players how we run things.
"It's unfortunate for Shane and he didn't do it on purpose but we've made it clear incidents like that cannot happen on game day.
