Walsh is scheduled to meet with Goodell at the NFL offices in New York at 7:30 a.m. Afterward, he will travel to Washington to meet with Specter, the senior Republican on the Senate Judiciary Committee who has been critical of the NFL's handling of the investigation.
Goodell and Specter each plan to hold a news conference after meeting with Walsh.
Last week, Walsh sent the NFL eight videotapes that showed the Patriots recording playcalling signals. The tapes included signals by coaches of five opponents in six games from 2000-02.
COURTS: In Miami, prosecutors said Monday they will not seek the death penalty against four people charged with murdering Redskins star Sean Taylor because the accused shooter was a minor when the crime was committed.
The U.S. Supreme Court has ruled that people cannot be executed for crimes committed when they're younger than 18, and it's a well established legal principle that others involved in the same case as a minor cannot face the ultimate penalty if they are less directly responsible.
BEARS: Robbie Gould became the NFL's highest paid kicker, agreeing to a five-year, $15.5 million contract extension through 2013 that includes a $4.25 million signing bonus.
Gould has made 84 of 99 field-goal attempts and 99 of 100 PATs with the Bears. He hit 31 of 36 field-goal attempts last season.
RAIDERS: Rookie running back Darren McFadden fumbled 23 times in three seasons at Arkansas, so extra emphasis is being placed on McFadden's ball security.
Raiders running backs fumbled five times last season, and the team has too many plans for McFadden to sit him for fumbling.
"Ball security, it's the heartbeat of our offense," Raiders coach Lane Kiffin said.
