Playmaker Matt Toomua knows Pocock's presence will be a massive boost for the Brumbies, who need to lift their game after two less-than-impressive performances against lowly teams.
"To have him in these big games and hopefully slow up their ball will be brilliant," he said.
"They like to play that really fast footy and with a guy like him either stealing the ball or slowing it down definitely plays into our hands."
The Highlanders found a way to limit Pocock's influence the last time they met in Invercargill in round 10, which they won 23-10.
It was also his comeback game from a two-match suspension.
"I'm sure they'll be focusing on him heavily - as you would," Toomua added.
"But that can provide opportunities for other guys. We've got more guys than just Dave, but in saying that, to have him back in such a great game is always a good thing."
