Paul Charnley's side were given a bye in the first round and won at Friar Lane & Epworth in the second round to set up this tie at Sphinx Drive tonight.
The final of this competition will be played at Walsall's Bescot Stadium and last season's final was won by Leamington FC.
Kick off at Sphinx Drive is at 7.45pm and after a mild night in Coventry, prospects look good for the game.
Match score updates will appear here later.
