Sources: Giants in on Matt Leinart

The New York Giants have been "investigating" all options for a backup quarterback for weeks according to Tom Coughlin.

And according to ESPN's Adam Schefter, the Giants have their eyes on Arizona's disgruntled quarterback Matt Leinart.

The Giants, Buffalo Bills and Oakland Raiders have had discussions with the Arizona Cardinals about trading for the recently-demoted Leinart, league sources tell the ESPN NFL Insider.

At least one member of the Giants and Raiders organizations had a conversation with the Cardinals this week, discussing the idea of trading for Leinart. It is unknown how serious each team is about Leinart, but the topic has been broached in the organizations, according to Schefter.

And an executive for an unidentified team told ESPN.com's Mike Sando that the Cardinals were calling around, trying to gauge the market for Leinart, who likely wants to start for another team.

The Giants need a veteran quarterback after placing backup Jim Sorgi on injured reserve Tuesday. Sorgi tore the capsule in his right throwing shoulder in the preseason opener against the New York Jets on Aug. 16.

Coughlin acknowledged Tuesday that the team is looking for a veteran but only for the right price.

"Well, it depends on what the availability and what the cost is," said Coughlin, whose team is off Wednesday before playing the New England Patriots on Thursday. "I'm not saying we're doing that [bringing in a quarterback], but our people are not caught by surprise by this [Sorgi]. Our guys have been working on this for a couple of weeks."

Second-year quarterback Rhett Bomar is currently Eli Manning's insurance. While he has shown toughness and flashes of potential, Bomar has never taken a regular-season snap after spending most of last season on the practice squad. Rookie free agent Dominic Randolph was brought in late in training camp to be the third-string quarterback.

Bomar, 25, will play most of the preseason finale against the Patriots in one final audition to show Coughlin he can be the backup quarterback.

"That's my goal," said Bomar, who was drafted in the fifth round out of Sam Houston State last year. "I want to be the backup on this team, and help the team out any way I can."

Bomar has completed 29-of-53 passes for 374 yards, two touchdowns and one interception. He's also rushed for 43 yards.

The 6-2 quarterback played the entire second preseason game against the Pittsburgh Steelers with Manning, who suffered a head laceration against the Jets, and Sorgi both out. Bomar went 13-of-26 for 167 yards and one interception in a 24-17 loss.

Leinart, 27, was expected to be Arizona's starter this season after Kurt Warner retired. But Cardinals coach Ken Whisenhunt has decided to start Derek Anderson in the Cardinals' preseason finale Thursday. It will be the second straight game that Anderson will start.

Leinart, who has completed 19-of-23 passes for 161 yards and one touchdown with no interceptions, met with Whisenhunt on Monday to air out any problems. Several reports have speculated that Leinart's days in Arizona are numbered.

Coughlin was asked if it is safe to assume he will wait to see how Bomar does against the Patriots before deciding to bring in another quarterback.

"I don't know if anything is safe," Coughlin said. "I just think that we're investigating all of our options, whatever those options are. If it comes that the decision is made after the game, fine. If it comes that the decision is made before that, fine, but all of the options are open, of course. Depending on if he goes in there and plays well on Thursday night, we'll certainly have good evidence to think that he can do it."
