Jets QB Sam Darnold had surgery on his left (non-throwing) thumb to repair a ligament, a source confirmed. It's a minor procedure and won't cause him to miss any time in the offseason. It happened in the Week 8 loss to the Jaguars and it affected his ballhandling at times. At the end of the season, Darnold said he didn't think surgery was necessary, pending further tests. The NY Post first reported the surgery.
