He would suffer a hamstring injury in November in a game against Stoke City, being replaced byMichael McGovern.[43] He proceeded to miss a number of games between then and the end of January, with McGovern orDaniel Barden deputising, but eventually regained his place as Norwich won the Championship and promotion back to the Premier League.
