For 31 other NFL teams, this would be an anomaly.
But, since it's the San Francisco 49ers, who've somehow developed a reputation for being a perennial league leader in injuries over the years, it painfully makes far too much sense.
All-Pro defensive end Nick Bosa suffered a calf injury during practice ahead of Week 3. On the tail of recovery from last year's ACL tear, the news is anything but good, and subsequent reports suggest he'll miss several weeks with the latest setback.
Normally, this would likely result in a trip to injured reserve—a minimum of four weeks off the active roster with the hope of returning to action once healed.
Except there's a problem.
The Niners have already designated 15 players to IR, and it's not even three weeks into the regular season.
It gets even worse, too.
49ers are running out of IR spots, putting them into awkward Nick Bosa situation
Now, teams can place as many players as necessary on IR. That's not the core issue. Instead, the problem is only eight players can revert back to the active roster from IR during any given season.
The rest have to stay on IR.
Several of San Francisco's players on the list are poised to return at some point:
- WR Christian Kirk
- OL Austen Pleasants
- LB Nick Martin
- CB Nate Hobbs
- DE Sam Okuayinonu
- WR De'Zhaun Stribling
- DT C.J. West
That's seven right there, and if Bosa goes to IR with an aim to return, the 49ers won't be afforded the opportunity to bring anyone else back, should they go to IR, too.
So, it makes sense why ESPN's Adam Schefter subsequently reported the Niners weren't fully committed to dropping Bosa off the 53-man roster and placing him on IR just yet.
The 49ers now are leaning toward not placing DE Nick Bosa on injured reserve in part because they’re running out of injured reserve spaces, per source. https://t.co/15vjNdar3L

If this is the case, what'd likely happen is Bosa would be listed as a weekly inactive over the duration of his injury. He'd still be counted for a spot on the 53-man roster, but at least San Francisco could activate another player who'd otherwise be unlikely to suit up for any given contest.
Granted, if Bosa is out for more than four weeks, it's less than ideal a scenario. It's also reasonable the 49ers opt to place some other less-essential injured players on season-ending IR, thereby removing the designation to return.
Either way, given the Niners' longstanding history of injuries, it's become almost comical they're dealing with injury-list gymnastics not three weeks into the season.
And Bosa's situation only puts a major highlight on just how problematic it's become.
