 Ahead of the 2010–11 season, Porter was confident that he and his fellow strikers at Derby made up "one of the best strike forces in the Championship", and that "injuries hindered the team's progress last season".He missed a portion of pre-season after requiring an injection for his troublesome hip, but returned for a 3–3 friendly draw with Bournemouth on 22 July.In his second appearance of the season, a 1–0 League Cup defeat to Crewe Alexandra on 10 August, Porter broke down with another hip injury, having to be replaced at half-time.
