Not as far as I know, but his debut match for New Cross was at West Ham. See below for extract from a forthcoming book...:
"One addition to the team came in the form of Cyril Roger’s brother, Bert, who was said to be at least as good a prospect as his brother, if not better. Bert was originally a road racer and finished 11th in the 1947 Isle of Man Junior T.T. In 1948, when his brother began to make a name for himself in speedway, Bert asked Mockford if he could try out as well. Mockford immediately saw his potential and signed him up, loaning him out to third division, Exeter to gain more experience. Although only in his first year as a speedway rider he topped the Exeter points chart with an average of 9.74, and Mockford recalled him to the New Cross side for the 1949 season.
"New Cross’s first league match of the season was against West Ham. Bert Roger astounded everyone by beating West Ham’s star rider, Aub Lawson, who was ranked number four in the world. This was Roger’s first-ever ride in Division One speedway. He also won his other race for a debut reserves’ maximum."
