Els said earlier this week that he would compete in the European Tour event.
Els is the only man to have won multiple Desert Classic titles (1994 and 2002) and holds the course record with a 61.
'I think everyone knows I love playing in Dubai,' Els was quoted as saying by the organizers. 'I like the lines off the tees and the greens are quite soft so if you get your ball up, you can shoot some good scores.'
The reigning European Tour Order of Merit winner, Els nearly claimed his third Dubai title last March, but his bid was thwarted by a final-round 65 by Dutchman Robert Jan Derksen.
