No, it was Greedo. It's what was shot on set, that was later re-written and re-worked in post after the Jabba scene was cut.
The only differences were in Greedo's dialogue, and one or two lines of Han's that were taken out completely, and it didn't have the "Even I get boarded sometimes" line (which was lifted from the Jabba scene). The scene was re-written in the script when they made the change (after shooting).
