'Grey's Anatomy' Season 10 spoiler: Is Richard Webber alive?

WARNING: Major spoiler alert for "Grey's Anatomy" Season 10. Read on at your own risk:

"Grey's Anatomy" creator Shonda Rhimes accidentally tweeted out a major Season 10 spoiler on Thursday (August 15) that's sure to relieve fans: Dr. Richard Webber (James Pickens Jr.) is alive!

In the Season 9 finale, fans will remember that the former chief's fate was left up in the air after he ended the episode unconscious in the flooded basement of the hospital, electrocuted after the power came back on in the wake of a huge superstorm. No one else in the hospital knew he was in trouble, so viewers were left in a panic that he wouldn't get the help he needed to live through any injuries sustained. 

But it looks like he will get help after all. The photo Rhimes tweeted was from the table read of "Grey's Anatomy's" 200th episode, and Pickens can be seen sitting with his fellow cast members. If his character did die, then why would he be present at the table read? He wouldn't, so obviously Webber will live. 

If you think that the above photo doesn't really reveal anything, Rhimes next tweet proves that she made a mistake:

Realizing that she accidentally revealed a major spoiler with the photo, she has since deleted both the photo and the tweet ... though our sleuthy friends at the Huffington Post managed to get a screen shot of both before they disappeared.

Rhimes' deletion of both tweets seem to prove that Webber does survive for Season 10, though that won't be surprising to fans who already knew that Pickens -- along with stars Ellen Pompeo, Patrick Dempsey, Chandra Wilson, Justin Chambers and the now departing Sandra Oh -- renewed his contract for two more seasons after Season 8, taking him through the end of this upcoming season.

"Grey's Anatomy" Season 10's two-hour premiere airs on Thursday, Sept. 26 at 9 p.m. ET on ABC.
