on a one-month loan, which was later extended until the end of the 2007–08 season. He made his début for Plymouth away to Southampton on 19 February 2008, with Plymouth winning 2–0. Anderson went on to play in all 14 of Plymouth's final league games of the season during his spell at the club. On 26 August 2008, Anderson joined Burnley on loan until the end of the 2008–09 season. He made his Burnley début on 30 August 2008 in a 0–0 draw against his former club Plymouth. Anderson played four consecutive league games for Burnley, but in his fifth game for the club, a League Cup tie against Fulham on 23 September 2008, he suffered a serious cruciate ligament injury that ruled him out for the rest of the season. After spending 14 months out injured, Anderson finally made his comeback in a reserve game against Wigan Athletic on 1 December 2009. Anderson's contract was due to expire at the end of the 2009–10 season. On 31 December, Anderson was reported to be in talks with Hibernian and an "unnamed Championship club", later revealed to be Derby County. However, Hibernian said they had no interest in signing Anderson, giving Derby County an advantage to win the race. Reports of Anderson leaving were confirmed on 14 January 2010, as Sunderland released him from his contract.

But I can't moan about what happened at Sunderland because it won't do me any good." Derby County On 15 January 2010, Derby County announced that they had signed Anderson on a contract until the end of the 2009–10 season. He made his début as a second-half substitute in a 3–0 win at Peterborough United the following day and appeared sporadically as a late substitute for the club over the next eight weeks, behind the club's first choice pairing of Jake Buxton and Shaun Barker. He finally made his first start for the club in a 2–2 draw with Middlesbrough on 16 March, in place of Buxton, and kept it for the rest of the season as Derby successfully fought off relegation. Anderson scored his first goal for Derby County, and his first in three years, on 17 April 2010 with the opener in a 1–1
