Coughlan, who played his first match in 99 weeks on Saturday after overcoming two knee reconstructions, was hoping to continue his comeback with another stint at VFL level for Coburg this week.
Tigers officials say he pulled up well from Coburg’s impressive win over Collingwood but is now set for another few weeks on the sidelines with his latest injury.
The Tigers released a statement on Wednesday afternoon, saying Coughlan “experienced soreness in his hamstring following today’s session at Punt Road Oval.”
It said: “The club expects Mark to miss several weeks. The club will continue to investigate all possible methods of rehabilitation to help Mark return to senior football.”
The setback comes as another blow for the courageous 26-year-old, who won the Jack Dyer medal in 2003 as the club’s best and fairest player.
