The San Francisco 49ers received a major boost today as one of their most promising defensive pieces finally returned. The team has officially opened his practice window, signaling the end of a long injury layoff. This news comes after months of uncertainty regarding his recovery timeline. Fans and coaches alike had been waiting for clarity, and this update brings optimism at a pivotal point in the regular season. Malik Mustapha, the 49ers’ high-energy safety, suffered a torn anterior cruciate ligament (ACL) in Week 18 last year. The injury abruptly ended his season and left him on the reserve list to start this one. Under NFL rules, the practice window lasts 21 days once activated. During this period, the 49ers can evaluate Mustapha’s progress and decide whether to return him to the 53-man active roster. Mustapha, a 2024 NFL Draft pick, showcased a fiery play style and decisive tackling ability in college. Throughout his NCAA career, he racked up dozens of tackles and was regarded as one of the most promising safeties in his class. Transitioning to the NFL, Mustapha impressed as a rookie in 2024, appearing in 16 games with 12 starts. He finished the year with 92 tackles (two forced fumbles), one interception, and five passes defended.Unfortunately, his professional path was interrupted early by the injury. Mustapha missed an important opening stretch, raising questions about his long-term durability despite his undeniable speed, strength, and determination. 👉FULL POST : https://x.com/_malikmustapha/status/1975333016068366400/photo/1  Head coach Kyle Shanahan confirmed the update earlier this week. “That has been discussed,” Shanahan said, emphasizing the team’s excitement to finally see Mustapha back on the practice field. For a San Francisco defense seeking added depth and explosiveness, Mustapha’s return couldn’t be better timed. If he proves his health, the young safety could be the spark the 49ers need to reinforce their defense for the season’s push.
