Defender Jack MacKenzie could make his Plymouth Argyle debut by the end of January.
The 25-year-old summer signing from Aberdeen has yet to kick a ball in anger for the Pilgrims.
Having suffered knee problems in pre-season, a number of other issues have prevented the 2025 Scottish Cup winner from featuring yet.
But he has begun full training and is returning to match fitness, meaning he could be in the squad when Mansfield Town visit Home Park on 27 January.
“He looked very sharp,” said head coach Tom Cleverley.
“He won’t be involved this weekend [at Peterborough], but with a plan to build that load next week, train pretty much every session with the team and I’d say more Mansfield than Luton [on 24 January].
“When you get to a new club you’re always keen to impress and there’s always a bit of embarrassment around not being available for so long.
“He’s worked his socks off, played a lot of games in the last few years for Aberdeen and he’s had some bad luck obviously since he’s been here.
“But he’s on the right track now. He’s going to be a couple more weeks but we’re looking forward to having him available.”
