The 38-year-old Argentine legend suffered an upper right leg injury early in Miami’s penalty-kicks home win over Mexico’s Necaxa in a Leagues Cup match.

The Herons have been reliant on their Argentine No. 10, and he pushed them to the last 16 of the Club World Cup, taking down Porto in the process. With Segovia and Tadeo Allende, there are other players who can step up to assist Luis Suarez in the attack, but Mascherano will need to determine the best setup if their star misses any time.

The Leagues Cup has brought Lionel Messi and Inter Miami happy memories in the past, but this season's edition has proven painful early on.
