The Trotters star is recovering from a serious knee injury inflicted by Manchester United's Jonny Evans in March and hopes to return in September.
But Trotters gaffer Coyle has warned Holden to listen to medical advice rather than rush his comeback.
He told the Bolton News: "Stuart's like a kindred spirit, so positive in his outlook and in everything he does. I love that about him.
"He's optimistic and he is improving no doubt about it but we have to make sure we pick the right moment to bring him back and not push him at all.
"Stu has targeted the middle of September. My medical lads are a wee bit more wary. If we get him back at that point I'd be thrilled, but we might just have to be a bit patient."
