It's their first clash since Pocock suffered his first ruptured ACL against the Waratahs in 2013.
Brumbies head coach Stephen Larkham earlier in the week hinted that Pocock would be eased back into Super Rugby from the pine when he praised the work current backrowers Ita Vaea, Jarrad Butler and Scott Fardy were doing in his absence.
"It is [a selection dilemma]," Larkham said.
"Certainly Poey adds that other element.
"A backrower who gets hard on the ball. It will be a slightly different look to our backrow when Poey gets on the field.
"But I look at the performances of our backrow, particularly on the weekend with Jarrad Butler, Ita Vaea and Scott Fardy all had fantastic games."
Brumbies captain Stephen Moore said the luxury of having named another unchanged side would help them against the Waratahs.
"It certainly helps having consistency through the group week in, week out," he said.
"Bringing David off the bench is exciting not only for him but for the rest of the boys, we all enjoy playing with him."
