Former Chester FC frontman Kane Richards arrived on a one-year deal in May.
The 22-year-old, who can also play on the wing, came through the ranks at his home-town club Derby County and signed a one-year professional deal before he was released in January 2013.
He then joined Ilkeston before signing for Chester in December 2014.
In that time, Richards made 69 appearances for the Blues, including 39 in the National League last season.
He scored eight times during his final season with Chester, three of those came in consecutive games.
