Lee, having spent his youth career at Korea University, entered the 2010 K-League draft intake, and was selected by Incheon United FC for the 2010 season. His professional debut came almost immediately, in Incheon's first K-League match of the season against the Chunnam Dragons. Substituted early in the second half, the match finished in a 1 -0 win for his new club. A month later, Lee scored his first goal in Incheon's 1 - 2 loss to Ulsan. Having established himself as a first choice starter at Incheon for the rest of 2010, Lee remained with the club for the 2011 season.
On 1 February 2012, Lee joined fellow league side FC Seoul, in a swap deal which saw Lee Kyu-Ro joining Incheon.
