James, who is spending his summer in Akron, tweeted a photo of himself leaving his house Thursday morning and wrote "time to serve my civic duty."
According to the Akron Beacon Journal, James drew a buzz at the Sutton County courthouse in downtown Akron when he arrived. He was not seated on a jury for trial and left the building at 10:30 a.m.
The league's reigning regular-season and NBA Finals MVP will go through the process again on Friday, the Beacon Journal reported.
