Robert Griffin III's marriage is just about over ... the NFL star has separated from his wife and the two are in the process of filing for a divorce ... this according to Cleveland.com.
The Browns QB married college sweetheart Rebecca Liddicoat in 2013 and just last year she gave birth to a baby girl.
But Griffin has reportedly told his teammates and coaches that the marriage has hit a wall -- and both parties are going their separate ways.
And get this ... RG3 has already scrubbed his Instagram page of all traces of Rebecca.
RG3 is said to be having a tough time with the situation -- but he's working through it with the support of family and friends.
