According to the Phoenix Mercury, DeWanna Bonner has been released from the hospital and will be re-evaluated day-to-day. Seth Pollack described the injury at SBN Arizona (linked above):

"In watching the play numerous times, I think the official got the call right.

Bonner jumps and makes contact with her body and then Zellous swings her left arm out and connects with the side of Bonner's face. I was told that DeWanna had a gash on the inside of her upper lip. In the replay we can see her head snap to the side."
