Blackpool's second signing of the 2013 summer made his debut in the opening day win at Doncaster Rovers.
Grant was signed for an undisclosed fee from Rochdale, after being Dale's top scorer last season in League Two with 16 goals.
His former clubs include Accrington Stanley and Scunthorpe United, as well as Rochdale.
The Pool number ten can play on either out wide or in the role just off the main striker and is predominantly left footed.
In his first season at Blackpool Grant made just seven appearances, as injuries kept him out for the majority, including during a spring loan spell to Fleetwood Town.
