Harlequins have confirmed fly half Nick Evans will miss the rest of the regular Premiership season.

The 35-year-old underwent surgery on a broken leg this week ruling him out of action until early May.

The former All Black faces a race against time to be fit for the Premiership play-offs should director of rugby Conor O'Shea's men qualify.

Evans, who suffered the injury in Saturday's 28-6 defeat at Gloucester, is one of five changes Quins have made to their starting 15 for Friday's clash with Leicester Tigers.

Dave Ward switches to his customary position of hooke rafter a spell on the flank, while Nick Easter returns at number eight.

James Horwill will skipper a team that will feature Winston Stanley at centre and Ben Botica in the number 10 shirt.

England Sevens scrum half Sam Egerton, signed in the week on a short-term deal as injury cover for Karl Dickson, will hope to make his debut from the bench.
