Toronto FC defender Drew Moor will miss at least one game after being diagnosed with a heart condition.
The MLS club announced Friday a cardiac arrhythmiawas discovered in Moor during a medical examination earlier this week and that more tests would be conducted next week.
"As precaution, Moor will not travel to Columbus for this weekend's match against Columbus Crew SC," a club statement read.
Moor, 33, is in his second season with TFC and 13th year in MLS. The U.S. international also has five caps with the national team.
The news of Moor's irregular heartbeat is similar to the issues that sidelined Seattle's Clint Dempsey for half of the 2016 season.
