The contentious personal relationship between Fox Sports Detroit’s top two Detroit Tigers broadcasters, Mario Impemba and Rod Allen, has boiled over.

The pair was involved in a physical altercation immediately following Tuesday night’s game against the White Sox, according to multiple persons with direct knowledge of the situation.

The sources requested anonymity because they were not authorized to speak on the incident, which was described as "severe" by one person who was present. Katie Strang of The Athletic was first to report the news.

When asked about the incident, Fox Sports Detroit general manager Greg Hammeran referred questions to Courtney Welch, the station’s director of social media and communications.

“We’re addressing an internal matter and will not have any further comment at this time,” Welch said.

It is unclear what led to the incident. Matt Shepard and Kirk Gibson called the series finale against the White Sox in their place.

Allen, a color analyst, did not file a police report, according to one person with knowledge of the situation. It wasn't immediately clear whether Impemba, the play-by-play voice, filed a report.

Neither Impemba nor Allen responded to a request for comment late Wednesday night.

Impemba, 55, and Allen, 58, traveled back to Detroit separately, one source said, and both are scheduled to meet with Fox Sports Detroit executives on Thursday to determine the next course of action.

The pair is in its 17th season broadcasting Tigers games together for the station. Though their on-air relationship has remained cordial, they are not considered friends off the air.

“I don’t think it was a secret,” one Fox Sports Detroit employee said.

Hammaran did not specify whether Impemba or Allen were suspended. Allen is not scheduled to work the next six games in the booth. However, he is scheduled to work the Tigers' pre- and post-game shows.

The Tigers are off on Thursday before opening a three-game series against the St. Louis Cardinals at Comerica Park on Friday. The team is scheduled to celebrate the 50th anniversary of the 1968 World Series champions during the series.
