The youngster was reportedly punched by James Morrison after a section of the squad vented their frustration at the striker for a late mistake in the 3-3 draw with Cardiff City
The youngster reportedly sustained facial injuries following a punch from Morrison on Saturday, with the Baggies playing down the incident on Tuesday.
Berahino has instead insisted that his sole focus is on on-field matters as 17th-placed West Brom look to move away from the relegation zone.
"I am not taking legal action against any team-mate. I am only focusing on Saturday's game at Norwich," he told the club's official website.
Richard Garlick, the club's sporting and technical director, added: "As we stated on Tuesday, the club has drawn a line under the matter.
"We have seven important games coming up and Saido, along with the rest of the squad, has a big part to play in them."
