Wallabies squad member back Mike Harris has suffered a hamstring injury during the Melbourne Rebels' Super Rugby clash with the Western Force.
Harris was recalled to the Wallabies to face England next month after a making his last appearance back in 2012.
However his series is now in doubt after suffering the injury while setting up the Rebels' opening try in the 12th minute, scored by Reece Hodge.
The five-eighth immediately left the field and was on the sidelines at AAMI Park with ice on the injury.
Harris has only managed two and a half games this season after injuring his quad in round one, also against the Force.
