The 25-year-old Argentine centre, who joined the club on a one-year deal in July, has been told that he will be unable to play for six months and so the club has allowed him to return home.
Glasgow Warriors head coach Gregor Townsend said: “We’re really disappointed for Gabriel that he’s had to leave the club early. He fitted in really well and would have played a big role in the second half of the season.
“Although he will not require surgery, he has been advised not to take any contact for six months, so we agreed to release him from his contract early to allow him to return home.
“We’d like to thank Gabriel for his contribution to the club during his time here and we wish him well for the future.”
