Brian Austin Green hasn't quite thrown in the towel on his marriage to Megan Fox ... he was spotted Thursday doing a little grocery shopping with his wedding ring on full display. 

Fox and Green announced they were separating August 19 and she filed for divorce a few days later.

Days after filing, Fox was out sans ring.
