Universidad de Chile is grappling with internal friction following the viral emergence of a social media post featuring striker Juan Martín Lucero. The club’s management has expressed significant annoyance over a video that showcased the Argentine forward undergoing an alternative recovery process for a muscle injury, sparking a debate over medical ethics and professional boundaries within the squad.
The controversy centers on a TikTok video posted by Adrián Atienza, a practitioner who describes himself as a specialist in “Neurobiomechanical Kinesiology.” In the clip, which has since been removed from the account, Atienza claimed to have drastically accelerated Lucero’s recovery from a muscle tear in his right leg, asserting that a rehabilitation period typically lasting three weeks was reduced to just three days.
For a professional sports organization, such claims are more than just a matter of publicity; they challenge the clinical protocols established by the team’s own medical staff. While the club was reportedly aware that Lucero was seeking complementary therapy, the public nature of the claim—and the implication that the club’s standard recovery timelines were inefficient—has created a rift between the player and the institution.
As a physician, muscle tears, or desgarros, involve the actual rupture of muscle fibers. Depending on the grade of the tear, the biological process of inflammation, proliferation, and remodeling typically requires a minimum of several days to weeks to ensure the tissue is strong enough to withstand the explosive force of professional football. A reduction of a 21-day window to 72 hours is an extraordinary claim that deviates significantly from established sports medicine benchmarks.
The Friction Between Complementary Care and Professional Ethics
The tension at Universidad de Chile does not stem from the use of external therapists, which is a common practice among elite athletes. Instead, the club’s frustration lies in the breach of professional discretion and the potential undermining of their own healthcare providers.

Club representatives indicated that while it is normal for players to work with private kinesiologists, massage therapists, and nutritionists, the behavior of the external practitioner in this instance was unacceptable. The organization specifically highlighted the impropriety of a private therapist issuing a public diagnosis and utilizing a patient’s recovery as a marketing tool on social media.
The club believes this public display leaves their own professional staff in a compromised position, suggesting a level of inefficiency that may not exist. The club has called Lucero in to provide explanations regarding the situation and the coordination of his private treatments.
A Pattern of Fragility
This incident adds a layer of complexity to Juan Martín Lucero’s tenure with the club. Having arrived as a key reinforcement intended to bolster the attack, the Argentine striker has struggled to maintain a consistent presence on the pitch. To date, his time with the team has been marked more by reports of injuries than by goals, leading to growing restlessness among the fanbase and the coaching staff.
The reliance on alternative treatments may be seen as a symptom of the player’s desperation to return to the lineup, but the resulting publicity has only increased the pressure on the forward. The club is now balancing the need for his talent on the field with the necessity of maintaining disciplined medical protocols.
Recovery Timeline Comparison
| Recovery Phase | Standard Clinical Timeline | Atienza’s Claimed Timeline |
|---|---|---|
| Inflammation/Protection | 3–7 Days | Included in 3-day window |
| Tissue Repair/Loading | 7–14 Days | Included in 3-day window |
| Return to Competition | 14–21+ Days | Day 3 |
Impact on the Upcoming Fixture
The timing of this controversy is particularly critical as the team prepares for its next match. The club is currently evaluating whether Lucero’s physical condition—regardless of the claims made in the TikTok video—is sufficient for him to be included in the squad for the upcoming clash against Deportes La Serena.
The match is scheduled for Sunday, April 5, at 18:00 hours at the Estadio Nacional, marking the eighth date of the Liga de Primera. Whether Lucero features in the match will serve as a practical test of his recovery and a signal regarding how the club has resolved the dispute over his treatment.
