The Patriots recorded signals of the Dolphins’ offensive signals during a game in 2001, a league source confirmed Friday, although it is uncertain whether the taping will result in further sanctions against New England and/or coach Bill Belichick.

ESPN.com reported Friday that one of the tapes submitted by former Patriots video employee Matt Walsh included the offensive signals. Previously, it was believed the Patriots had taped only opposing teams’ defensive signals.

As a result of the Spygate episode, which began when the Patriots were caught videotaping the Jets’ defensive signals in a Week 1 game last season, Belichick was fined $500,000, the team was docked an additional $250,000, and the Patriots’ own first-round pick in 2008 was forfeited. The team had another first-round choice acquired in a 2007 trade with San Francisco.

League spokesman Greg Aiello said Friday that it was “premature” whether any of the information Walsh submitted to the NFL will result in further sanctions of Belichick or the team. However, Aiello confirmed that the penalties that resulted from last season’s investigation into the Patriots’ videotaping procedures covered defensive and offensive signals. It is unclear whether Belichick informed the league that he had also taped opposing teams’ offensive signals.

One of Walsh’s tapes was of the AFC Championship Game after the 2001 season, in which the Patriots beat the Steelers. The existence of that tape had already been known, and the league informed Sen. Arlen Specter (R-Pa.) about it. Steelers owner Dan Rooney called the taping of those signals a “non-issue.” The Patriots had included the existence of that tape in notes they provided the league in September.

The key to whether Belichick or the team faces any further penalties may rest with the fact that there was no tape of a walk-through of the Rams’ practice the day before the Patriots’ first Super Bowl win after the 2001 season. A report in the Boston Herald said the Patriots had taped the Rams; however, Walsh provided no such tape.

Belichick has consistently denied he taped the practice. Had there been a tape of that practice, there is a likelihood that NFL commissioner Roger Goodell would have slapped Belichick with a lengthy suspension, perhaps for a year. There is a good chance Belichick would have lost his job over such a tape, since it went beyond the taping of opposing teams’ signals.

Walsh is scheduled to meet with Goodell on Tuesday morning to discuss the content of all of the tapes.

Walsh and Goodell are expected to address the media after the meeting.

Patriots’ Andrews pleads to drug offense

LOWELL, Mass. – New England Patriots defensive back Willie Andrews entered a plea to a marijuana possession charge, but won’t face any prison time.

The 24-year-old Andrews admitted in court Friday there was enough evidence to convict him at trial, but did not plead guilty. Lowell District Court Judge Neil Walker continued the case without a finding for a year. During that time, Andrews must speak to student athletes about the dangers of narcotics, pay a $1,000 fine and complete an NFL substance abuse program.

Andrews was arrested in February after police pulled him over in Lowell. Prosecutors said he had $6,800 in cash on him, a half pound of marijuana and no means to smoke the marijuana.

Andrews’ attorney, Sean Delaney, declined comment on the plea.

Patriots spokesman Stacey James had no comment.
