Cesc Fábregas has been ruled out of Arsenal's Champions League clash with Porto tomorrow because of a hamstring problem, meaning another day in the Arsenal Hospitality Tickets.

The midfielder limped off after scoring the opening goal in the 3-1 win over Burnley on Saturday. The tightness was in the same hamstring he injured earlier in the season, which kept him out at the turn of the year.

The Arsenal manager, Arsène Wenger, said: "We cannot even take a gamble, so he is not available."

Sol Campbell did, however, join in training and he looks set to recover from a groin problem in time to face the Portuguese side, who will take a 2-1 lead to the Emirates Stadium for the second leg of the last-16 tie.
