Greys Anatomy co-stars Patrick Dempsey and Isaiah Washington nearly came to blows during a heated argument on the set of the award winning TV series.

Dempsey, 40, and Washington, 43, didn’t need medical aid, but the actors, who both play renowned doctors on the show, nearly came to blows during a spat over shooting issues.

“We were like two baseball players . . . nose-to-nose,” Washington tells PEOPLE. “We had a difference of opinions while working on set but we’ve resolved it.”

At issue, says Washington, was “time and (keeping) the production going. The communication was lost in translation.”
