made his debut for the club in a 0–0 home draw against Harrow Borough. He made seven appearances for Aylesbury, playing his last game for the club in December 2002, a 1–1 draw away to Basingstoke Town. Day returned to the QPR first–team towards the latter stages of the 2002–03 season. He played in goal for the rest of the season, and was part of the team that lost 1–0 in the play–off final to Cardiff City in the Millennium Stadium. Day played 34 times for QPR during the 2003–04 season. He kept 16 clean sheets from August 2003 to February 2004; including five clean sheets in six matches during November 2003. He sustained an injury in February 2004, which meant QPR signed Lee Camp on loan to cover in his absence, and his Camp's form ultimately kept Day out of the team when he returned. Day was an unused substitute in QPR's 3–1 win against Sheffield Wednesday, a victory that ultimately secured automatic promotion back to the Championship. Day returned to the first-team for the club's return to the Championship during the 2004–05 season, playing 33 games. He was dropped in January 2005 in favour of loanee Simon Royce, and was, as a result, allowed to move to Preston North End on a one-month loan deal. He made his Preston debut in a 2–0 defeat to Nottingham Forest, as well as making five more appearances for the Lancashire club; keeping two clean sheets during his time there. Oldham and Millwall Having played two more games for QPR on his return, Day was allowed to leave for Oldham Athletic a week before the start of the 2005–06 season. He became the first-choice goalkeeper at Boundary Park, playing 36 games during the season and keeping ten clean sheets. Then manager Ronnie Moore took the opportunity to sign out of favour Derby County goalkeeper Lee Grant on loan at the end of the January transfer window, and Day subsequently became second-choice for the remainder of the season. Day left Oldham at the end of the season and opted to sign for Millwall in June 2006. He made his Millwall debut in a 3–2 defeat to Cheltenham Town two weeks into the start of the new season. Day played seven times during Millwall's 2006–07 campaign, six times in the league and one further appearance for Millwall in the Football League Trophy. He regained
