With the return of the Test players for the 1950–51 season, Davidson had to perform strongly when given opportunities in order to hold his position. He started his season productively by taking 7/49 in the first innings of the opening match against Queensland, including the wickets of Test players Ken Archer, Colin McCool and Don Tallon, but he expressed disappointment at his erratic line and length, frequently bowling full tosses and long hops. New South Wales won by an innings, and Davidson took four wickets in the return match, but results began to dry up thereafter. He had the opportunity to show his skills against Test opposition as New South Wales played England ahead of the Tests, but he went wicketless, and was dropped in December after the next match against Western Australia. Davidson ended the season with 14 wickets at 22.71 and 42 runs at 10.50 from four matches.
