The 49-time Canada international signed a two-year deal with the Saddlers in July 2016.
Born in Jamaica, the 29-year-old forward grew up in Canada before moving to England with Rushden & Diamonds, where he scored 42 times in 93 appearances.
He continued to find the net at his next club Gillingham, plundering 42 goals in two seasons, and was snapped up by Norwich for £600,000 in 2010.
Jackson spent three years with the Canaries and scored the goal that clinched their promotion to the Premier League in 2011.
After spells with German side Eintracht Braunschweig, Millwall, Coventry, Barnsley and Blackburn, Jackson joined Walsall last summer and netted seven goals in his debut season.
