The American was forced to undergo surgery last week after suffering a fourth serious knee injury but he has refused to concede that he might have to call time on his playing career.
Holden told US podcast Soccer Morning: "I'm just ready to get back on the horse. It was obviously a setback, disappointing for me personally and a lot of emotions were flying around, but I'm well and truly feeling like I'm ready to do this thing again.
"I won't give up because I know I have a lot left to give the game. I know my work-ethic, my mentality - that will all get me there again. I'm fully confident in my medical team where I'll be playing again with no problems."
