记者：因伤落选的马斯坦托诺仍加入阿根廷队的训练营（记者：因伤无缘名单的马斯坦托诺仍随阿根廷队集训）

Asking for clarification

I should ask if the user wants details, sources, translations, or a summary regarding Franco Mastantuono. It's likely he was dropped from the Copa America due to a muscle injury, but he's still training with the national team for rehab and integration. We don't have network constraints for sourcing, but I should summarize generically. I'd like to propose options, such as translating to English, providing player background, or discussing the impact on the Argentina squad. Let's keep it concise!Clarifying information carefully

I need to avoid providing incorrect specifics while sharing what I think is the most likely name. It’s better to phrase it cautiously, like saying "it is reported that..." or asking for confirmation. I’ll share minimal information with the following points:

• Brief explanation: The player may have missed the Copa America due to injury, but is still training with the team, indicating rehabilitation under supervision.

• If you’re referring to Franco Mastantuono from River Plate, please confirm.

• Let me know if you'd like me to: 1) summarize reports, 2) write a smooth news piece, 3) create bullet points, or 4) translate.
