EAST RUTHERFORD, N.J. – The New York Giants thought it was possible that two potential starters in the secondary would return for Sunday’s game in London against the Los Angeles Rams. Cornerback Eli Apple still appears on target, but safety Nat Berhe suffered a setback.

Berhe did not complete Wednesday’s practice, according to coach Ben McAdoo. He was trying to return after missing the past three games with a concussion.

“Not so well,” McAdoo said of how Berhe did at practice. “We had to pull him out.”

Berhe remains in the league’s concussion protocol. He had tweeted on Monday that he was cleared to return to practice. But he never made it through a practice.

“He was limited and, yes, he’s still in the protocol,” McAdoo said. “He never got to a contact practice.”

This again puts Berhe's status in serious doubt and has undrafted rookie Andrew Adams in line for another start. Adams has held his own in his three starts this season.

Apple, meanwhile, had a solid day of work and appears destined to return after missing last week’s win over the Baltimore Ravens with a groin injury. He said he practiced without any physical limitations, although the Giants kept him out of some late drills as a precaution. They're bringing him along slowly, in part because the groin injury follows a hamstring problem.

But the first-round pick feels significantly better than last week, when he wasn't that far off from playing against the Ravens.

“He moved around well in the work he got,” McAdoo said of Apple's performance at Wednesday's practice.

Apple was still listed as a limited participant along with linebacker Keenan Robinson (ankle) and cornerback Trevin Wade (ankle).

Star wide receiver Odell Beckham Jr. (hip) and long snapper Zak DeOssie (ankle) were not outside at practice. Safety Darian Thompson (foot) and right tackle Marshall Newhouse (calf) didn’t practice but stretched with the team and did some light work with trainers. They’re both eyeing post bye-week returns.

The Giants play the Rams on Sunday and then have a week off.

Beckham's injury is not expected to be serious. He is expected to play Sunday.
