The centre half has been out for around nine months, suffering an ACL tear in March against Manchester City.
This was the second severe injury for Botman, who was a revelation for the Magpies when fit.
Speaking at his pre-match press conference for Newcastle’s game against Brentford in the Carabao Cup, Howe said: "He was good last night (60 minutes for the club’s Under-21 side against Chelsea’s Under-21s), he seemed in a good place, we exchanged messages.
"His movement was good, commanding, and a big presence on the pitch. We have missed him. That was a good step for him to get back on the pitch.
"We are looking at the end of December or start of January, give him a few more games to get him back on track.”
