Week 2 in the NFL has been extremely unkind to the health and longevity of its star players, and Nick Bosa of the San Francisco 49ers is among the victims of the flood of injuries.

The star defensive end had to be carted off the field at MetLife Stadium in the team's matchup with the New York Jets. Now head coach Kyle Shanahan says the team fears Bosa, last year's Defensive Rookie of the Year, has a torn ACL, per ESPN's Nick Wagoner.

The 49ers defeated the Jets on Sunday despite multiple injuries to the team including Bosa, Jimmy Garoppolo, and Raheem Mostert.

Early in Sunday's game versus the Jets, Bosa was carted off after sustaining what appeared to be a knee injury. Seeing that it was a knee ailment, the first thought that crosses everyone's mind is a torn ACL.

The second-year defensive end will undergo further testing before the team reaches an answer on what they'll need to do with him. Of course, if the tests do confirm what is feared by Kyle Shanahan and the team, then Bosa would be done for the rest of the season.

Losing Bosa for the season would leave a large void in San Francisco's defense. As a rookie, Bosa was able to notch nine sacks, 16 tackles for loss, 25 quarterback hits, and a forced fumble. In Week 1, the reigning Defensive Rookie of the Year six tackles, a quarterback hit, and a forced fumble.

To make matters worse for the 49ers, they experienced a handful of crucial injuries against the Jets. Besides Bosa, San Francisco also witnessed injuries occur to Solomon Thomas, Raheem Mostert, and Jimmy Garoppolo. Not to mention, entering Week 2, the 49ers were already without George Kittle, Deebo Samuel, Dee Ford, and Richard Sherman.
