Brandon Jacobs among running backs to try out for Giants on Tuesday

While the Giants try to fix their new running back, they might be bringing back one of their older models.

Brandon Jacobs, the team's fourth all-time leading rusher, will be among a group of players at the Giants facility Tuesday for free-agent tryouts.

"I'm open and objective about whatever," coach Tom Coughlin said of the workouts, a routine Tuesday activity during the regular season made more relevant by the presence of Jacobs and Wilson's fumbling issue. "Whenever we have a workout, I'm comparing that individual to what we have and we'll see what [Tuesday] brings. We continue to evaluate at multiple positions."

Jacobs won't be the only running back brought in for a test drive. Willis McGahee and former Jet Joe McKnight will also reportedly be present. The Giants also worked out a group of running backs last week but did not sign any. Two of them have re-signed with their former teams: Leon Washington with the Patriots and Jonathan Dwyer with the Steelers.

The Giants waived defensive end Adewale Ojomo on Monday, so they have a spot on their roster to sign any player who catches their eye.

Jacobs visited the team during training camp and told people then that he was in shape and ready to play if needed. He wasn't then, but after Andre Brown fractured his leg, the Giants began working the running back Rolodex.

Eventually, they got to their old slammer, who was released by the team following the 2011 Super Bowl-winning season. He was on the 49ers roster for parts of last year but hardly played, never seemed to fit in, and was waived before the playoffs.

"I would like to take this time to thank all of the fans who have been behind me all this time," Jacobs wrote on Twitter Monday, acknowledging his workout for his former team. "I'll go out tomorrow and give it all I got . . . I wanna be back with big blue I can't let the opportunity pass me by."

Meanwhile, the Giants are far from giving up on Wilson despite the noncommittal status of his place on the depth chart. His two fumbles came a year after he coughed up a ball in last year's opener as a rookie. That sent him to the bench for most of the season. This time, the Giants have no such luxury.

"I've already said we need him," Coughlin said.

Fumbling issues are nothing new for running backs under Coughlin. He famously "fixed" Tiki Barber and helped improve Ahmad Bradshaw's technique.

"We've been down this road before," Coughlin said. "We think we can have an impact on him being a better ballcarrier, a better secure ballcarrier. We'll get that done."

Notes & quotes: Coughlin said cornerback Prince Amukamara, who left Sunday's game with a concussion just before halftime, was feeling better but will have to complete the NFL protocol before returning to the field . . . Coughlin said claims by the Cowboys that the Giants faked injuries to slow the Dallas offense are "absolutely not true." He noted that linebacker Dan Connor left the game and did not return after his injury, a burner. He seemed to have less defense for the injury to defensive tackle Cullen Jenkins that had Tony Romo complaining during the game. "Cullen was in a position where he needed to regroup," Coughlin said. "That really wasn't orchestrated at all."
