Texas Tech's Jordan Barncastle fouled Griner with Baylor (No. 15 ESPN/USA Today, No. 14 AP) leading by 16 with 9:01 remaining in the game Wednesday night.
Barncastle had been playing aggressive face-up defense against Griner and the two players were struggling for position in the post before the incident, according to media accounts of the game.
After she threw her shoulder and arm at Griner, Barncastle was moving away when the Lady Bears' standout drew back and landed a punch to Barncastle's face.
Griner likely faces additional discipline from Baylor and the Big 12 conference.
"There's no place for that in sports," Baylor coach Kim Mulkey said. "It was

The game was stopped for about 10 minutes as officials reviewed tape. A technical foul was called on Griner and she was ejected for a flagrant foul, and another technical was called on another Baylor player, Morgan Medlock. She got into a heated exchange with Texas Tech's Ashlee Roberson, according to reports.
Barncastle, who went to the Texas Tech locker room after the incident to exchange her bloodied jersey for a clean one, returned and shot four free throws, making all four. She then left the game and didn't return.
Barncastle and Griner exchanged words in the teams' first game, Feb. 17 in Waco, according to media reports. Griner scored 19 points and grabbed 10 rebounds in that game, a 65-48 Baylor win.
Texas Tech coach Kristy Curry said Barncastle has an appointment Thursday morning to determine the extent of her injury.
"We're all in shock right now," Curry said. "It's very unfortunate. It's very sad. My only concern is Jordan Barncastle."
Barncastle was not available to the media following the game.
The Texas Tech bench also got a technical for going out onto the court after the punch was thrown.
Griner had 21 points before being ejected. Baylor beat Texas Tech 69-60.
Baylor has one regular-season game left, at home Sunday against Texas (No. 22 ESPN/USA Today, No. 18 AP). That game could have ramifications for the Big 12 conference tournament, which starts Thursday in Kansas City.
The top four seeds are awarded first-round byes, and Baylor is currently tied with Texas, Texas A&M (No. 14 ESPN/USA Today, No. 15 AP) and No. 20 Oklahoma State for fourth place with 9-6 conference records.
