Weitering suffered an AC joint injury in Round 11, which required the star defender to undergo surgery and was originally set to miss six weeks.
However, after a quicker-than-expected recovery and an increase in his training, 3AW reporter Sam McClure revealed that an early return next week could be on the cards for Weitering.
"Track watchers are telling me today that Jacob Weitering is not far away from playing in that game and that would be unbelievable.
"He's been doing some serious sessions on the track."
Weitering had an excellent first half of the season, with many having the former number one pick in the All-Australian conversation, cementing his stake as one of the best key defenders in the league.
An early return for Weitering would be a major boost for the Blues, whose defence has thinning each week as more players suffer injuries.
Important defensive figures like Oscar McDonald (back), Mitch McGovern (hamstring), Zac Williams (calf), Caleb Marchbank (knee) and Sam Durdin (knee) are all absentees for Carlton, so Weitering's return will help relieve some pressure.
However, Voss' side will be without Weitering for an important clash this weekend, as they face the in-form Dockers at Marvel Stadium on Saturday afternoon (1:45 pm AEST).
