Rookie left tackle Ereck Flowers sat out Monday's practice with a sore hip flexor, but Tom Coughlin said he does not think the injury is too severe.

"He doesn't seem to be bad," Coughlin said after the practice. "This morning he was sore, but by the time I caught him in the meeting room, he was doing this [swinging his leg]. Hopefully, it's just a short amount of time."

The Giants are calling Flowers day-to-day. Coughlin said the injury occurred a few days ago and Flowers tried to play through it.

With Flowers out, the Giants had Justin Pugh slide from left guard to left tackle. That's the position he played in college before he was drafted by the Giants and was moved to right tackle for two seasons. This is Pugh's first season working at guard, although Jerry Reese has mentioned him as part of the team's depth at tackle.

"We thought today would be a good day to put him at left tackle," Coughlin said of Pugh. "His versatility, he's a smart player, it's helpful."

The Giants also gave Geoff Schwartz a handful of reps at right tackle along with his usual ones at right guard. Adam Gettis took Pugh's spot at left guard with the starters.

Fracas upsets Coughlin

After the most spirited practice of camp thus far, a brief but action-packed fistfight between Pugh and Damontre Moore, along with a play in which aggressive pass rushing led to Eli Manning hitting the ground, had Coughlin grousing about the risk of injuries in those situations. "I have a problem with all of them because they're out there swinging," he said of his aversion to fights in general. "I've been hurt firsthand by a guy who broke his hand in a fight . . . I was upset about the fight and losing their temper and all that stuff, but the bottom line is you can't afford to do it. You'll lose a guy."

Manning's spill was more accidental, but Coughlin said it needs to be avoided. "It's all the same, it's all related the same way," he said. "He was kind of stumbling around and you always talk about stay away from the quarterback, stay away from his feet. We've had some careless rushes, to be honest with you. Not many, but a couple."

Manning was not on the turf very long. Several linemen, both offense and defense, quickly yanked him to his feet. "They were smart," Coughlin said.

Giant steps

Cornerback Chykie Brown left practice early with what Coughlin said was a foot injury or a shoe issue . . . Trevin Wade made a nice leaping interception in practice . . . Manning threw a bomb to a wide-open Odell Beckham Jr. for a 60-yard touchdown . . . The Giants do not have practice Tuesday. They are scheduled to be in full pads Wednesday in a practice that is not open to thepublic because of an event at MetLife Stadium.
