Some were sold and some were sent out on loan.
The PT has had a look to see how they’ve been getting on, good or bad
9. BEN THOMPSON
The little midfielder moved to Stevenage for an undisclosed fee in the summer and he's been in and out of his new club's starting line-up. Thompson has started five of 13 League One matches and come on as a substitute in five other games. He's collected more yellow cards (2) than goals (0). Photo: David Lowndes
10. KABONGO TSHIMANGA
The striker joined League One rivals Fleetwood Town on loan for the rest of the season on transfer deadline day. Tshimanga couldn't get a game for Posh and little has changed since his move as he has started just one League One game so far. He did score two close range goals in a 3-3 EFL Trophy draw at Wigan earlier this month though. They were his first goals in nine months. Photo: Joe Dent
11. CHARLIE O'CONNELL (and others)
The 20 year-old defender played two senior games for Posh this season before moving on loan for the third time to National League Woking at the start of October. He's played 20 minutes as a substitute for the Cards so far. Other youngsters to have left Posh on loan include centre-back Ashton Fox, who has been excellent at Peterborough Sports, left-back Aaron Powell who is back at Posh after six appearances for National League North side Bishop's Stortford and midfielder MacKenzie Lamb who is at Southern Premier Division Central side Alvechurch, making 10 first-team appearances so far.
