It was a fifth international appearance for the 23-year-old, who touched down in Ospreys' thrilling early-season 29-29 draw with RaboDirect PRO12 champions Leinster.
Davies, who plays his RaboDirect PRO12 rugby for Scarlets, will now face a lay-off and Beck's deployment on Saturday would suggest he is the natural successor to the Welsh number 13 shirt.
And with Argentina visiting Cardiff this weekend he is excited by the prospect of lining up at outside centre and alongside a handful of his RaboDirect PRO12 teammates.
"I'll play in the front row if they ask me to," he told the South Wales Evening Post. "I'm ready to get on there and play.
"I enjoyed playing against South Africa, even though we lost. It was nice to get back on the field and play rugby again. Hopefully, I'll be able to build on that, but we'll just wait and see with the selection.
"It was a very physical game. We were unlucky in the end not to get anything from it. I wouldn't say South Africa were out of this world.
"If you just take the last try out of it, it would have been 17-15 going into the last ten minutes and anything could have happened.
"I thought our front five were brilliant. I'm lucky enough to play alongside Richard Hibbard, Alun Wyn Jones and Adam Jones every week and those boys are always the same."
