49ers' Solomon Thomas Could Have Torn ACL After Knee Injury vs. Jets

San Francisco 49ers defensive end Solomon Thomas was carted off in Sunday's game against the New York Jets with a knee injury and is feared to have a torn ACL.

49ers head coach Kyle Shanahan told reporters Thomas needs further examination to verify the extent of the injury.

The 25-year-old went down in the first quarter, not long after Nick Bosa was also carted off the field with what Shanahan said was likely a torn ACL. He had two tackles before exiting. 

Now in his fourth NFL season, Thomas had struggled to perform at the level necessary for a No. 3 overall pick. The Stanford product has only six sacks through his first 46 games and saw his role adjusted amid the arrivals of Bosa and Dee Ford. 

Thomas did not record a tackle in Week 1 despite being a starter on the defensive line. If Bosa and Thomas are out, however, the 49ers' vaunted front seven could be in trouble.
