Brisbane’s Anthony Milford has been ruled out for at least a month after suffering a grade two hamstring tear at NRL training on Monday.

The maligned five-eighth has battled with form this season but his injury will come as a blow for the Broncos before their grudge match with South Sydney on Friday night.

Milford left training early on Monday clutching his hamstring and scans on Tuesday revealed a tear.

It comes amid calls for coach Anthony Seibold to dump the underperforming star after the Broncos last week lost their ninth game from their past 10.

“It’s unfortunate but as a result we expect Anthony to be out of action for at least the next month,” Broncos Head of Performance Paul Devlin said.

“He will start rehabilitation in coming days and will build his strength back up before commencing his return to run program.”

Injuries have cruelled Brisbane this season with regulars Matt Lodge, Alex Glenn, David Fifita, Brodie Croft and Corey Oates all sidelined at various points.

Fifita is set to make his return to the field for the first time since round two on Friday night, while Croft is expected to be named alongside Tom Dearden in the halves.
