September previously indicated he would hang up his boots after 2015/16 due to a combination of injuries and limited game-time.
However, the 33-year-old has started to feature more regularly for Matsatsantsa since Baxter replaced Gordon Igesund as coach of the Tshwane club in January.
Baxter has opted to deploy September in central midfield, with the player previously featuring at the back.
"I am enjoying the role. The coach has shown great faith and belief in me," September tells snl24.com/kickoff.
"I have started to enjoy football again and it has renewed the hunger of playing football. It will all depend if SuperSport United make an offer of allowing me to play again, I might consider continuing playing football again next season.
"It is always a great feeling to wake up every day and join the guys for training."
September has already started preparing for life after football. The former Mthatha Bucks defender, who holds a diploma in sport management, has been earmarked for a managerial position at SuperSport, while he has business interests in addition to running the Thabo September Foundation.
