Head coach Pat Shurmur said Sunday night the Giants didn't "know how bad it is."
In Engram's absence, Rhett Ellison caught three passes, including a 16-yard touchdown that gave the Giants a 20-3 lead over the Texans.
In good news for the Giants, it appears running back Saquon Barkley will not miss time. He was hit on the knee on his first carry and left the game for the next series. Barkley said after the game he took a "pretty good hit but was able to fight through it."
