Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: BASIC_SCIENCE
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* no neurological or psychiatric disease~* recent history of concussion (\<3 months) according to the Rugby French Federation criteria.~Exclusion Criteria:~* Inability to be assessed by MRI

- Gender: MALE
- Minimum Age: 18 Years
- Maximum Age: 35 Years
- Healthy Volunteers: t

Study Arms:
- Concussion Group (Type: EXPERIMENTAL): Players with a recent (\<72 hours) history of concussion will be assessed 3 times. just after concussion, after disappearance of clinical symptoms and 3 months after the previous visit. During each visit, participant will undergo a neurological and a neuropsychological assessment and a structural and resting state fMRI.
- Control Group (Type: ACTIVE_COMPARATOR): a control group with no history of concussion will be the comparator. Participants will be assessed 3 times. Visits will be the same for the control group and duration between visits in this group will be matched to the concussion group. During each visit, participant will undergo a neurological and a neuropsychological assessment and a structural and resting state fMRI.

Based on this trial design, predict the completion outcome and termination type (if applicable).
