Jon Wallis

Although normally a central midfielder, Wallis made his debut at right back in the Football League Trophy match at home to Crawley Town. Gillingham won 2–0 that night in a game that went to extra time and Wallis played exceptionally well in an unfamiliar position. In particular, Wallis showed a willingness to get forward to support the attack, and was involved in the thick of the action when he cleared a goal-bound effort during normal time.

Wallis joined Conference South side Dartford in 2011 after a falling-out of a number of players with then Dover manager Martin Hayes.

After Dover Athletic won the Isthmian League Division One South title, Wallis opted to sign a new one-year deal in May 2008. The following season saw more success for the Kent club as they won the Isthmian League Premier Division at the first time of asking, which prompted Wallis to sign another new contract for Dover Athletic.

On 27 March 2007, he left Hereford by mutual consent and subsequently signed for Dover Athletic until the end of the season.

Andy Hessenthaler was appointed Dover Athletic manager in June 2007, and Wallis turned down a Football League club in order to spend at least another year at the Kent club to develop his game under the former Gillingham manager.

Wallis went on to make around twenty performances in the 2005–06 season, almost entirely at right-back, however on 9 May 2006 he was released by Gillingham and a few weeks later signed for Hereford United. However, he made only two substitute appearances for the Bulls.

On 28 October 2006, he went on loan to Dover as midfield cover, making 12 appearances and scoring his first goal of the season in the 4–0 win over Ashford Town. On 19 February 2007 he went out on loan again, this time to Dagenham & Redbridge, making two substitute appearances.

He progressed through the youth ranks at Gillingham and signed his first professional contract, at the beginning of the 2005–06 season. Prior to this he had spent three months work experience at Hastings United where he made 14 appearances in all competitions, scoring four goals. Two of these goals were in the preliminary rounds of the FA Cup. He returned to the Pilot Field in September 2005 on a month's loan. Back at Gillingham, Wallis had been a mainstay in the youth and reserve teams and it was following some strong performances in the reserve team that Neale Cooper decided to hand Wallis his debut.
