Major League Soccer (MLS) will be among several leagues in the United States to introduce concussion substitution trials for the 2021 season, the country's football federation said on Monday.

U.S. Soccer, alongside a concussion task force made up of representatives from organisations including the MLS and National Women's Soccer League, agreed to implement the rule, which will allow teams two additional concussion replacements, regardless of the number of substitutions already used.

"Adopting this new rule is an important step as we continue to lead the way in player safety," U.S. Soccer Chief Medical Officer George Chiampas said in a statement.

"It was critical to come together as a sport with our professional leagues and proceed in this pilot program, prioritizing the well-being of our players above all.

"We've worked hard to raise awareness of head injuries in soccer over the last several years, and this change should go a long way in protecting players suspected of suffering a concussion."
