Wes Welker's Wife Anna Rips Ray Lewis -- He's a TERRIBLE PERSON

12:00 PM PT -- Anna just posted an apology ... "I apologize to Ray Lewis and his family for my comments. In no way did I mean for them to be mean or hurtful. I'm embarrassed for being a sore loser. I wish Ray and the Ravens good luck. Lesson learned!"

Wes Welker's wife hates Ray Lewis ... and not just because the Ravens beat the Patriots yesterday ... it's 'cause she thinks he's a terrible human being ... and she made her feelings known on Facebook.

After Sunday's AFC Championship game ... Anna Burns Welker went to her Facebook page and posted the following message:

"Proud of my husband and the Pats. By the way, if anyone is bored, please go to Ray Lewis' Wikipedia page. 6 kids 4 wives. Acquitted for murder. Paid a family off. Yay. What a hall of fame player! A true role model!"

The post has since been deleted.

FYI -- Lewis was charged with murder back in 2000 for his involvement in a fight that resulted in two deadly stabbings ... but the murder charge was dropped as part of a plea deal.

Oh yeah, the four wives thing ... Lewis has never been married -- but he does have six kids with four different women.

And you don't want to get on his bad side.

Fact is, Anna should've known better -- because last year after the Super Bowl, Tom Brady's wife Gisele Bundchen blasted Wes Welker for dropping a key pass ... and people trashed her for it.
