Images of Dibu Martinez and his jaw protection after violent head collision

Martinez returned to training with Argentina after jaw surgery following a collision with Everton's Branthwaite on 17 October; he will wear protective headgear during recovery.

Emiliano Martinez suffered a serious head collision with Everton defender Jarrad Branthwaite on 17 October and underwent successful jaw surgery. Initially sidelined for over a month, the Chelsea goalkeeper has recovered faster than expected and rejoined Argentina's squad for friendlies against Uruguay and Costa Rica.

Argentina's medical staff confirmed Martinez has progressed well through rehabilitation and resumed training at Chelsea last week. He trained normally with the national team on Friday and Saturday and is nearly ready to play, though he will wear a protective helmet throughout his recovery as a precaution.

While Martinez is available, manager Lionel Scaloni is unlikely to risk him in the friendlies, with Geronimo Rulli expected to start. The final decision on his participation will depend on how he feels and coordination between Chelsea and the national team's medical teams.
