New England Revolution sporting director and head coach Bruce Arena has been placed on administrative league as Major League Soccer reviews allegations he made "insensitive and inappropriate remarks."

The league offered no further in formation in a brief statement on Tuesday, when the Revolution offered a brief statement of their own.

"The organization takes any allegations of workplace misconduct extremely seriously and is working closely with the League and fully cooperating with its investigation," the club said.

Arena, 71, is a former US national team coach and a four-time MLS coach of the year.

He has coached four MLS teams -- DC United, the New York Red Bulls, the Los Angeles Galaxy and the Revolution and won MLS Cup titles in 1996 and 1997 with United and in 2011, 2012 and 2014 with the Galaxy.

The Revolution are scheduled to play Mexico's Atlas on Wednesday at Gillette Stadium in Foxboro, Massachusetts, in the round of 32 of the Leagues Cup tournament featuring MLS and Liga MX teams.
