Walker will undertake a 10-day intensive training course under Knowles' watchful eyes and will be joined on the trip by Crows physio Duncan Kellaway.
Kellaway met Knowles, who is based in Philadelphia, through a colleague while working with Geelong before following coach Brenton Sanderson to West Lakes in 2012.
The list of Knowles' past clients is a who's who of world sport and includes Woods, McGrady, NFL star Payton Manning, English rugby legend Johnny Wilkinson and Chelsea's Frank Lampard.
Walker told the Crows' website he was optimistic the rehab specialist's strengths in helping injured athletes recover their acceleration would aid his return from a knee reconstruction.
"It's going to be for 10 days, two sessions a day, so Monday to Friday and have the weekends off, then Monday to Wednesday," Walker said.
"I'm looking forward to getting over there; he's big on acceleration, deceleration and jumping and landing.
"Hopefully he can hold me in good stead to get back."
The 23-year-old has made significant progress from his horrific knee injury sustained against Carlton in round five at the MCG.
He began running on Adelaide's anti-gravity treadmill late in the 2013 season and has since managed to run unaided outdoors.
Walker said he was excited to get as much of the pre-season under his belt as possible and line up in a new-look forward line.
Several players including Lewis Johnston and Tom Lynch impressed in attack this season and with the addition of former Carlton star Eddie Betts, Walker will return to a vastly changed offensive unit.
“A few boys have had opportunities this season. Lewis Johnston and Tommy Lynch had chances and took it with both hands,” he said.
“Hopefully, we can build a strong unit down there going forward and, hopefully, win a flag with it.”
