Collins (neck/concussion) did not practice Wednesday, Dan Salomone of the Giants' official site reports.

EDGE Analysis

Collins was designated to return to practice Dec. 10, but he has trended negatively since. He suffered a setback Friday that prevented him from playing in Week 15, and it was also enough to keep him sidelined Wednesday. Collins will seemingly have to make a significant step in his recovery to be ready for Sunday's game against the Vikings.
