Messi suffered the injury against Sevilla on October 20.
But Marca claim he might be fit for a place on the bench in the Champions League Group B clash at the San Siro on Tuesday – just SEVENTEEN days after breaking his arm.
Barca have won every game in his absence – including the 5-1 thumping of bitter rivals Real Madrid in last week’s El Clasico.
However, they laboured to a 3-2 victory at Rayo Vallecano on Saturday night, with Luis Suarez and Ousmane Dembele scoring in the final three minutes.
While Messi could be available for the Inter match, it remains to be seen whether he will be risked by manager Erensto Valverde.
His side need only a point to guarantee their place in the last 16.
One more win from their final three games would see them go through as group winners
Inter, though, should not be underestimated and go in to the game in excellent form.
They are second in Serie A and have lost just once – to Barcelona – in their last ten games in all competitions.
Luciano Spaletti’s free-scoring side have bagged eight goals in their last two games – winning 3-0 at Lazio and 5-0 at home to Genoa.
Messi’s fellow Argentina star Mario Icardi has been key to their recent good form, with eight goals in 11 matches.
Icardi had never played in the Champions League before the current campaign.
And he has two goals in three appearances in the competition.
