It was at the end of the season that Zlatan Ibrahimovic injured his knee.
An injury that made him miss the European Championship play-off with Sweden this summer.
Ibrahimovic has been gone for four months.
But now he is recovered and ready for a comeback.
When Milan presented the squad for tonight's match against Lazio, the striker was in the squad again.
Milan have won their two opening matches in Serie A and are in fifth place in the table and Ibrahimovic will be a welcome addition for the team.
Lazio has also started the season well and has won its two matches.
The team is in second place in the table.
