"It's a great tribute to a great man," Barfield said of the jersey idea, which was initiated by the Reds' Ken Griffey Jr. "It's cool to see everyone around the league wearing it. I'll be honored to wear it."
The Indians are petitioning Major League Baseball for the right to pay a similar tribute to Larry Doby, who became the first black player in the American League when he suited up for Cleveland on July 5, 1947.

There will be more I'm sure, but here's the list of players I've seen so far that will be honoring Jackie Robinson. Ken Griffey Jr, Gary Sheffield, Barry Bonds, Derek Lee, Willie Randolph, Dmitri Young, Mike Cameron, Carlos Lee, Josh Barfield, Coco Crisp and Orlando Hudson. CC is also going to wear the number on the bench. Barfield probably wouldn't be wearing it if CC was scheduled to pitch that day.
