The American international has been sidelined since injuring his knee in the CONCACAF Gold Cup final in July.
And after a number of previous spells out injured, Holden is now back on UK soil to finish his rehabilitation work with the Bolton medical team.
“I’m feeling good right now,” Holden said. “We had a bit of a nightmare flight back from the US on Sunday but managed to get back in time to watch the Wigan game with the fans.
“It’s always a cool experience when you’re sitting with the away fans. It’s a reminder of how passionate they are and I owe a lot to them for the support they've shown me.
“To see the team play again was nice. I've obviously been away for a few months to get fit. I’m now back to continue my end-stage rehab with the medical staff and move towards playing competitive football.
“I’ve been doing a lot of work with a really good personal trainer in LA, Holly Silvers. She’s really got me on a great path and helped me get over the initial disappointment of being injured.
“Once I got over that initial setback which I had not anticipated I was fully focussed on getting fit. That’s what my last five months have been designated towards and I’m really happy with my progress.
