Bulldogs centre Josh Morris will miss this Sunday's clash with the Wests Tigers at ANZ Stadium (4-10pm), after suffering a lateral ligament knee injury in last Sunday's loss to the Sharks.
Morris, who scored his 100th NRL try for the Bulldogs in the match, will not need an operation, but is likely to be sidelined for up to six weeks.
His place in the side will be taken by John Olive, who moved to the Bulldogs this season from the Gold Coast Titans.
21 year-old Olive played one NRL match for the South Sydney Rabbitohs in 2015, before appearing 9 times for the Titans over the past two seasons.
Raymond Faitala-Mariner has also recovered from a hamstring strain and returns to the starting 17.
