Sydney Roosters prop Lindsay Collins will take a break from playing in the NRL after suffering concussions in two consecutive games.
Queenslander Collins sustained a head knock in State of Origin III before getting concussed in last week's NRL win over Manly for the Roosters.
Collins hasn't been named in the Roosters side that will face Brisbane at the SCG on Thursday.
"It will be a couple of weeks," said Roosters coach Trent Robinson.
"It's hard because science doesn't know what the answer is.
"We've seen when we've given a few weeks off to guys they've come back better."
