The Congolese winger has been sidelined for almost a year after rupturing his cruciate knee ligament, an injury that required successive surgeries to repair the damage.
Bolasie, who posted images of him resuming light training at Finch Farm a few weeks ago, is now set to rejoin his team-mates in the first team tomorrow but he still does not have a set date for when he can return to competitive action.
“I haven't set a date yet for that return. I can't really say right now,” Bolasie told Sky Sports News.
“I'm back in on Monday at Everton. I'm probably going to be integrated with the team then, but comeback I don't know.
“I want to make sure I'm feeling good. It's not just my name on my shirt on the pitch; I want to make sure it's me.”
Bolasie was signed for £28m from Crystal Palace last year but made just 15 appearances before he was struck down the injury.
