With the Giants’ star receivers either out or slowed by hamstring problems, the unheralded trio of Dwayne Harris, Geremy Davis and Myles White has gotten the spotlight in practice this week.

Davis is a rookie sixth-round pick and the three have just 55 career receptions among them, so they’re not likely to strike fear in the heart of the Eagles if they have to play a lot of snaps in Monday night’s NFC East showdown in Philadelphia.

But the Giants put on a brave face Friday at the possibility of Harris, Davis and White being their receiving corps in a nationally televised game with Big Blue’s sole possession of first place in the division on the line.

“Yeah, we’re confident in those guys,” offensive coordinator Ben McAdoo said. “Geremy has been around here since the offseason. Myles has been in the system for a while, [or at least] a form of the system, and he’s blended in nicely. … So we’re not going to pull back, we’re not going to pull any punches. We have confidence in those guys, and they’re champing at the bit.”

It probably won’t come to that. Although Victor Cruz (calf) won’t be back for the Eagles, Rueben Randle practiced Friday and appears likely to play against Philly. Odell Beckham Jr. was held out of the non-contact workout, but it would be a surprise if his hamstring problem keeps him out entirely.

But if Randle and Beckham have unexpected setbacks between now and Monday, the next in line are convinced it won’t kill the Giants’ hopes against the Birds.

“All of us were in on that final drive against San Francisco, and that turned out pretty well,” Harris said Friday, referring to himself, Davis and White on the Giants’ game-winning march with Randle sidelined and Beckham limited.

“We’ve got talent, and Eli [Manning] is such a pro that he’s comfortable throwing to anybody,” Harris added. “So I think we’ll be in good shape however it turns out.”

The Giants are off Saturday but will practice again Sunday, and coach Tom Coughlin said he hopes Beckham’s hamstring can allow him to participate.

Coughlin won’t make that mandatory for his star wideout to play against the Eagles, though.

“It would be good if we knew in advance, so we could think a little about that,” Coughlin said. “Yeah, that would be good. Does it preclude [him from playing if he doesn’t work]? No.”

Sam Bradford is off to a slow start in Philadelphia, much to the dismay of Eagles fans, but Bradford got a big vote of confidence Friday from the coach who originally drafted him No. 1 overall — Giants defensive coordinator Steve Spagnuolo.

“We believed in him when we took him in 2010, I still believe in him now and I think he’s really kind of finding a groove here, unfortunately for us,” said Spagnuolo, who was coach of the Rams when they took Bradford.

“It takes a lot for people in systems to get used to it, and I always felt he was a very accurate thrower and still is.”

The Giants could get a heavy dose of DeMarco Murray on Monday after the Eagles made fellow running back Ryan Mathews a late addition to their injury report with a groin problem.
