The Seattle Sounders announced on Friday that star striker Clint Dempsey will skip this Sunday’s rivalry game against the Portland Timbers in order to undergo medical evaluations for an irregular heartbeat. More from the team’s statement:

“As the medical process unfolds and information is gathered internally, no other details are being made publicly available at this time.”

According to general manager and team president Garth Lagerwey, the Sounders have been monitoring Dempsey’s medical condition for some time, so let’s just hope that these are precautionary tests and that nothing serious comes out of this and that he is able to make a speedy return to the field.

A U.S. Soccer spokesperson also told ESPN’s Jeff Carlisle that Dempsey won’t be called up by Jurgen Klinsmann for World Cup qualifiers against St. Vincent and the Grenadines (Sept. 2) and Trinidad and Tobago (Sept. 6). This means he won’t be back until the Hexagonal round of CONCACAF qualifying, should the Americans advance past the fourth round (U.S. sits in second place — three points back of Trinidad and Tobago in Group C). Dempsey’s last USMNT appearance came during the Copa America Centenario where he scored three goals and led the team to a fourth place finish.
