Andre De Grasse and Asbel Kiprop headline a Diamond League meet in Stockholm, live on Sunday starting at 9:15 a.m. ET on NBC Sports Gold and 10 a.m. on NBCSN.
De Grasse, the only man other than Usain Bolt to earn three sprint medals in Rio, will look to break 10 seconds in the 100m for the first time since the Olympics.
Meanwhile, the 2008 Olympic champion Kiprop runs his first international 1500m race of the year. Kiprop went into the Rio Games as the favorite but finished sixth.
