Ghana midfielder Kevin-Prince Boateng does not believe the injury suffered in last night�s 2-2 draw with Barcelona in the Uefa Champions is serious.
The 24-year-old year was replaced by Massimo Ambrosini just after 34 minutes at the Camp Nou.
Boateng aggravated the shoulder injury he sustained in last Friday�s Serie A opener with Lazio after a challenge with a Barcelona player.
The former Portsmouth man is confident he will return to action sooner than later.
He tweeted: �My injury won�t keep me out for long�
Boateng must be fit for AC Milan�s trip to Napoli on Sunday.
