BEREA, Ohio (AP) — For the first time as Cleveland’s coach, Kevin Stefanski didn’t have to wear a mask on the field. Stefanski took off his COVID-19 mask during rookie minicamp after the NFL announced it has eased some of its protocols. Fully vaccinated personnel are not required to wear their masks at team facilities. Before the workout, rookie linebacker Jeremiah Owusu-Koramoah said he’s not worried about a heart issue that may have caused some teams to pass on him in the draft. Owusu-Koramoah said his heart is “100% healthy” and that it is not an issue. The Browns opened their rookie minicamp on Friday with 18 players on the field.
