Jason Lokilo has put pen to paper on a permanent one-year deal at Rovers.
The 21-year-old joined Rovers on loan in January 2020 and had just started to break into the starting XI when the season was suspended due to the COVID-19 coronavirus pandemic.
The winger made a big impact on his debut when his cross was turned in for an own goal to help Rovers secure a 3-1 win again Wycombe Wanderers.
