Upon signing, manager Ove Pedersen called Lumb "mentally very strong" and stated that he needed to work on "getting his career back on track". A few days later, OB director of sports Jesper Hansen revealed, that he had negotiated a contract with Lumb, but that the latter had eventually decided to sign with Vestsjælland. He made his debut for the club on 21 July in a 1–1 league draw against Brøndby. He suffered a knee injury in December 2013, which required surgery. He was, however, able to play most of the games during the spring on pain killers. He finished the 2013–14 season with 30 total appearances, as FCV ended in ninth place in the league table, six points clear of relegation. In June 2014, Lumb had surgery for his persistent knee injury, with the first reports being that he would be sidelined him for some months.
