Sea Eagles second-rower Justin Horo believes the Broncos aren’t going to be an easy assignment on Sunday despite their impressive record at Suncorp Stadium.

Manly have only lost one of their past seven matches at the venue and have won nine of their past 11 matches overall against Brisbane.

But history will count for nothing on Sunday, according to the Manly second-rower. 

“They’ve been really gritty this year. They started really well and in the games that I’ve watched they defend their line really well and they work really hard for each other,” Horo said.

“We’re going up to Suncorp and it’s always a big occasion when you play up there, it’s always a big crowd and I’m sure just after Origin everyone will still be buzzing a bit, so it’s going to be a big game.”

The Sea Eagles are set to welcome back captain Jamie Lyon and five-eighth Kieran Foran this Sunday, and Horo believes their injection will provide a massive boost in their quest for a fifth straight win over the Broncos.

"They looked pretty good out there (at training). It will obviously come down to Andrea our physio, Donny and the staff to see how they pull up at the end of the week. A bit of contact work is the biggest thing for them but they looked good today," he said.
