Engram (calf) was listed as a non-participant on Monday's practice estimate, Dan Salomone of the Giants' official site reports.
The Giants just held a walkthrough Monday, but Engram would not have been able to participate had they held a practice. With a short turnaround before Thursday's game against Washington, Engram looks likely to miss a second consecutive contest to open the season, though he's yet to be ruled out at this point.
