Ritchie underwent further specialist assessment but the Scottish Rugby Union says he is now fit enough to travel and will join the rest of the squad at their training camp in Nagasaki on Thursday.
Bradbury was given a place among the substitutes in Scotland’s 36-9 win over Georgia despite being one of eight men cut by head coach Gregor Townsend and came off the bench to replace Ritchie.
Bradbury, capped eight times, had missed the three prior warm-up Tests with a rib problem. Scotland open their World Cup campaign against Ireland on September 22, with Japan, Samoa and Russia their other Pool A opponents.
