Thibodeaux’s ACL and meniscus remained intact, and the Giants hope the first-round pick will be ready for their regular-season opener against the Titans on Sept. 11, the source told Schefter. Thibodeau suffered the injury in Sunday’s preseason game against the Bengals when he was tackled in the second quarter by Cincinnati’s Thaddeus Moss.

Thibodeau immediately grabbed his knee and left the field, but the former Oregon star later told reporters he was “fine.” The No. 5 pick in this year’s NFL draft, Thibodeaux has had a strong summer and had a quarterback pressure earlier in Sunday’s game. The Giants expect big things this season from Thibodeau, who has been working with the first-string defense since OTAs began in the spring. Thibodeau had 19 sacks in 30 career games at Oregon and entered last season as the likely No. 1 prospect in college football. ESPN’s Jordan Raanan contributed to this report.
