Gold Coast have underlined their status as NRLW premiership contenders by ending Wests Tigers' five-game winning streak in an emphatic 58-0 victory.
But they may have to count the cost of locking up second spot as rugby sevens convert Teagan Levi injured her nose and failed her HIA after an ugly tackle from five-eighth Losana Lutu.
The Titans (9-1) knew a win at Campbelltown Sports Ground on Sunday would propel them four points clear of third-placed Brisbane and earn them a home preliminary final with one round remaining.
Gold Coast had scored six unanswered four-pointers, including a hat-trick by centre Jaime Chapman, before Levi left the field on the stroke of halftime.
The visitors shook off the loss of their star playmaker, running in four more tries to register the second-largest victory in competition history.
The Tigers (7-3) will sweat on captain Kezie Apps (leg) and rising star Faythe Manera (knee).
Their humbling also put them in a perilous position. After Parramatta won a thriller in Canberra later on Sunday, the Tigers must beat the Raiders on Friday or risk missing out on a home elimination final.
Earlier, fullback Tamika Upton produced another sparkling performance to power Brisbane to a 24-16 victory over St George Illawarra.
The reigning Dally M Medallist continued to push her case to claim back-to-back gongs at Win Stadium, scoring a try, assisting two others and chalking up 226 run metres.
Upton's efforts also opened some breathing room between the Broncos (7-3) and their rivals, boosting the defending premiers' hopes of earning a home elimination final.
But Upton won't be happy with her side after they committed a mammoth 16 errors, despite the fullback giving them a verbal rev-up at halftime.
The teams traded tries to start the game, but two moments of brilliance from Upton set up back-rower Lauren Dam and centre Georgia Bartlett.
After her side led 18-6 at the break, Upton burst through a hole and stormed over, before Dragons winger Shenae Ciesiolka and halfback Kasey Reh crossed for consolation four-pointers.
For St George Illawarra (2-8), the loss keeps them equal on points with last place, and they'll play fellow strugglers Cronulla (2-8) next Saturday in a potential decider for the wooden spoon.
Sunday's late game was an absolute thriller, with Rachael Pearson nailing a 70th-minute field goal as Parramatta claimed a 17-16 win over the Raiders at GIO Stadium.
Rory Owen scored a double and Boss Kapua scored her first NRLW try for the Eels (3-7), but it was the side's defensive effort that stood out.
The Raiders spent much of the match camped in attacking territory, but struggled to break down the Eels' defensive wall and were held up over the line several times.
The loss means the Raiders' bid for a maiden finals berth will go down to the final round, with Canberra (5-5) needing a win over the Tigers on Friday night to secure a spot in the top six.
