Portland Trail Blazers shooting guard Wesley Matthews will not be in the lineup on Thursday night against the Golden State Warriors after undergoing an electrical cardoversion procedure on Wednesday afternoon, via a Blazers press release.
According to the team, Matthews was experiencing an irregular heartbeat on Wednesday. He left practice halfway through and then had the procedure. His heart rate is now back to normal, but he is listed as day-to-day and did not travel with the Blazers to Oakland for their final preseason game.
Judging by the fact that Matthews compared himself to Iron Man via Twitter, it seems he should be fine.
