Unión received alarming news this Tuesday, mainly because of Lautaro Vargas’ situation. The club released the medical report on defender Joaquín Mosqueira and Ignacio Malcorra, but the focus remained on the right back, who apparently suffered a very serious injury.

“Lautaro Vargas: the player suffered a severe sprain to his left knee. He will be reevaluated daily, and depending on his progress, the course of treatment will be determined,” the club officially reported.

Around midday, Ignacio Pettinari reported that the young player developed at Defensa y Justicia may have suffered an injury to his cruciate ligaments. This could be confirmed after a series of medical tests that have already been scheduled.

If this is confirmed, Vargas would be sidelined for between 6 and 9 months if he undergoes surgery and rehabilitation, although full graft maturation and final clearance for high-risk sports could take up to 12 months.

Can Unión sign another player?

The regulations allow a club to request a replacement when a player suffers an injury with an estimated recovery time of more than four months, provided a series of requirements are met and the injury occurs within the authorized competition period.

In addition, the request must be reviewed by the AFA Sports Medicine Department, which may call in the player, request additional tests, or wait for surgery to take place before determining whether the injury actually requires more than four months of recovery.

If AFA’s Executive Committee approves the request, Unión would have five business days to complete the paperwork and register the replacement, with the possibility of a one-time extension of another five business days, which must also be authorized by the Executive Committee.

An important detail is that the replacement does not necessarily have to play in the same position as the injured player. The only exception is that the position must be respected when it involves a goalkeeper.

Therefore, if Vargas is ultimately ruled out for an extended period, Unión would not be required to use that spot exclusively to bring in another defender. The club’s management could assess the market and decide which position it considers the priority to strengthen the squad.
