MADRID, April 15 (Reuters) - Barcelona striker Henrik Larsson will miss Tuesday's first leg of the Champions League semi-final against AC Milan because of a thigh injury, the Primera Liga club said on Saturday.
The Swedish international limped off the pitch just nine minutes into a 1-0 victory over Villarreal at the Nou Camp on Friday.
Larsson's replacement Santi Ezquerro followed him down the tunnel 25 minutes later after suffering bruising to his right knee and is doubtful for Tuesday's match at the San Siro.
League leaders Barca will also be without Argentine international Lionel Messi, who is expected to be out of action for at least another three weeks with a thigh muscle tear.
Brazilian forward Ronaldinho, who has been rested for the past two league matches because of a minor thigh injury, has been given the all-clear to play.
