Glenn has been ruled out of Friday night’s Suncorp Stadium clash with South Sydney.
Herman Ese’ese will make his Broncos debut off the bench.
Bennett wasn’t happy after Glenn failed to recover from a hip flexor injury sustained when he copped a knee from Newcastle’s Sione Mata’utia in Brisbane’s 53-0 last round win.
Bennett said injuries caused by knees were becoming a huge concern and he wanted it addressed by the NRL.
“That’s the third one for the season for us, that type of incident,” Bennett said.
“I didn’t like any of the ones I have seen and Saturday night was in the category.
“I wanted to see if they (match review committee) did anything about it (Mata’utia’s tackle) but I am going to make a phone call today.”
Glenn finished the game against Newcastle but at one stage spent more than 20 minutes off the field receiving treatment for the injury.
Bennett admitted he did not know how long Kiwi backrower Glenn would be sidelined.
“Another week, I don’t know,” he said.
“There is a huge bruise from his ribs down to his lower leg.
“Everyone knows that the two hardest parts of our bodies are our elbows and our knees.
“Players have to take more responsibility for their actions in certain situations.”
Sam Thaiday will move into the starting backrow while Ese’ese – who made his NRL debut at the Bulldogs last year – will slot onto the interchange.
Form winger Corey Oates (knee) was cleared to play after completing Thursday’s training.
Ladder leaders Brisbane are aiming for their fifth straight win.
