The injury-hit US international is planning to continue his career with Bolton Wanderers once back fit and healthy.
Holden, 29, was hailed as one of the building blocks of the US national team upon moving from the Houston Dynamo to Bolton Wanderers in 2010, but his well-documented injury problems have seen him suffer a broken leg, fractured femur, two ACL tears and various setbacks since.
His latest comeback attempt last March lasted just 23 minutes into a Bolton under-21s game before his knee would break down again and require another operation, with his contract going on to expire in the summer.
The former MLS star has since been working as a pundit back in the States as the continues his rehabilitation, but has revealed that he still plans to return to the Macron Stadium in the future, with manager Neil Lennon confirming in November that the door is open for him to re-join the team when he feels the time is right.
Writing from his official account, Holden declared: "Anytime I'm on TV, I get the inevitable 'Get back on the field, why are you on TV so much' shout from friends and foes.
“All I can say is that the process of healing takes time and a man needs to eat! I think everybody can agree at this point that it would be detrimental to push this faster than need be, trust me, this is the hardest part.
"I'm sure MOST are aware by now that I have NOT been under contract with Bolton since July 2014.
“While my plan is still to return to action with the club (COYW!), I've taken this opportunity to further my footsteps in the TV world and prepare for life after football (whenever that may be).
“It's something I certainly enjoy doing and hope to do post-career, but not ready to do it full time quite yet!
“I thank you for your continued support.
“Look out for a comprehensive video on the behind the scenes of my rehab/daily life coming in the next two weeks by Arch Rivals FC.”
Holden made 34 total appearances for Bolton between 2010 and 2013, and was voted the club’s Player of the Year in 2011 despite missing the final two months of the Premier League season with a broken leg.
It remains to be seen whether the 25-times capped international will ever be able to replicate that form, but one still wouldn’t want to bet against him given the determination and perseverance he has shown throughout his past fitness battles.
