Nightmare Start: 49ers Rookie Mikail Kamara Tears ACL at Practice
49ers Rookie Mikail Kamara Suffers Season-Ending Knee Injury
What Happened?
San Francisco 49ers rookie defensive end Mikail Kamara suffered a serious knee injury during practice on Saturday. Here’s the simple breakdown:
- The injury: Torn ACL (anterior cruciate ligament) — one of the main ligaments that keeps your knee stable
- How it happened: During a regular practice session
- Immediate result: Had to be carted off the field (couldn’t walk on his own)
- Official diagnosis: Confirmed by team reporters on Sunday
IMPORTANT POINT
A torn ACL typically requires surgery and 6–12 months of recovery time. This almost certainly ends Kamara’s rookie season before it even begins.
Who Is Mikail Kamara?
Kamara has an interesting football journey:
College Career Highlights
- Played 6 seasons under the same coach, Curt Cignetti
- 4 years at James Madison University (FCS powerhouse)
- Transferred to Indiana for his final 2 years when Cignetti became head coach there
- Big moment: Named Defensive Player of the Game in the College Football Playoff National Championship Game last season
NFL Journey
- Went undrafted in the 2025 NFL Draft
- Signed with the 49ers as a free agent
- Expected role: Compete for a roster spot as a pass rusher (gets after the quarterback) and special teams contributor (plays on kickoffs, punts, etc.)
What Happens Next? (Step by Step)
- Waived with injury designation — The 49ers officially released him from the active roster on Sunday
- Clears waivers — Other NFL teams have 24 hours to claim him (unlikely since he’s injured)
- Reverts to Injured Reserve (IR) — He goes on the 49ers’ IR list for the rest of the season
- Surgery & rehab — He’ll have ACL reconstruction surgery, then begin a long rehabilitation process
- Returns in 2026 — Goal is to be ready for next year’s training camp
Why This Matters for the 49ers
- Lost depth at defensive end — Kamara was fighting for a backup role
- Special teams impact — Undrafted rookies often make teams through special teams; that path is now gone
- Roster math — Opens a spot for another player to compete in camp

FAQ
What is an ACL and why is it a big deal?
The ACL (anterior cruciate ligament) connects your thigh bone to your shin bone and keeps your knee from wobbling. When it tears, the knee becomes unstable. Surgery + months of rehab are required — it’s one of the most serious common sports injuries.
What does "waived with an injury designation" mean?
It’s an NFL procedure. The team cuts the player, but flags that he’s hurt. If no other team claims him within 24 hours, he goes back to his team’s Injured Reserve list. The team still pays his salary but he doesn’t count against the 53-man roster.
Can Kamara play for another team this year?
No. Once he reverts to the 49ers’ Injured Reserve, he’s locked to their IR for the entire 2025 season. He cannot play for anyone else.
What does "undrafted free agent" mean?
He wasn’t selected in the NFL Draft. After the draft ended, he was free to sign with any team. The 49ers chose him. Undrafted players face longer odds to make the final roster.
Will the 49ers sign someone to replace him?
Very likely. Teams usually bring in another player to fill the practice/training camp spot so the remaining players don’t get overworked.
