Raiders head to the Worcester University Arena with an 18-point advantage, having impressively won the first leg at the Pavilions 96-78.
Around 100 Raiders fans are expected to make the trip up to the West Midlands to support their team and, hopefully, cheer them to victory.
With Daryl Corletto leading the scoring in the first leg with 23 points and Cory Dixon just behind with 22 points, it has put Raiders in the box seat to make the final in Glasgow on March 19 against either Leicester Riders or Cheshire Phoenix.
Raiders last reached the BBL Trophy final during the 2011/12 season, but lost to Newcastle Eagles.
For basketball fans unable to travel to Worcester on Friday night, the semi will be shown on the BBC Sport website and via the red button.
