After losses to Aldershot and bottom side Northampton, the Dons looked set to suffer another painful reverse when Gary McDonald headed the Shrimps ahead after 52 minutes.
Yussuff had other ideas, though, and after collecting substitute Billy Knott’s pass he fired AFC Wimbledon level, leaving Morecambe to hang on for a draw.
After an uneventful opening 10 minutes, some great play between Yussuff and Jack Midson allowed the latter to shoot from distance only to be denied by Morecambe’s fit-again ‘keeper Barry Roche.
The Shrimps opened the scoring seven minutes into the second half when a cross from Danny Carlton found McDonald, whose header from inside the penalty area fell beyond Seb Brown.
And that looked to have settled matters until Yussuff’s well-taken 75th-minute equaliser. The home side then hit Morecambe with a barrage of pressure in the closing stages but the visitors’ defence stood firm.
