The winger is recovering from a knee injury in December.
Dyche said, "Aaron Lennon is coming along well and feeling good about himself and his injury. He's in a good place.
"There are a lot of challenges on that side of things, but the group keep pulling together and keep realigning and doing what they need to do."
Lennon is back out on the grass and running strongly, Dyche thinks he is the closest to a return.
"He has a chance, depending on the next week, 10 days, he's not trained with us, but he's out there running, and usually that's a strong sign.
"He's properly running, not just trotting around in your running shoes, he's working now, and we hope to not have to rush him, but it's important we get more people fit, for their welfare as well don't forget."
