The tentative lineups are out for the USA vs. World Series at the Penn Relays and Usain Bolt is slated to anchor the Jamaica Gold team in the 4 x 100-meter relay at 2:50 this afternoon.
Joining Bolt on that relay team are Mario Forsythe, Yohan Blake and Marvin Anderson.
The Jamaicans and the Americans have two teams in the 4 x 100. USA Blue will be anchored by Ivory Williams and Rae Edwards will run the final leg for USA Red.
If you're not here already, you may have trouble finding a seat. Franklin Field is filling up fast in anticipation of Bolt's appearance.
