Newcastle co-captain Jamie Buhrer will be given until the end of the week to prove his fitness after being selected in the Knights' side to face Canberra despite taking a heavy knock in the first week of the season.

Knights coach Nathan Brown has named the same 17 that defeated Manly Warringah Sea Eagles in a thrilling round one encounter, with the only concern over the interchange player.

"Jamie Buhrer is carrying a bit of a knock and how doubtful he is we will probably know more tomorrow," Brown said.

"We named him because we certainly think he's a genuine chance of playing.

"So, I'd say JB is the one that's most in some sort of doubt.

"He got through some training today but how he pulls up tomorrow will probably determine that."
