That person provided no details on the deliberations other than indicating the Redskins still have a chance to sign Talib, who finished last season with the New England Patriots and formerly played for Redskins secondary coach Raheem Morris while with the Tampa Bay Buccaneers.

However, another person with knowledge of the Redskins’ situation said it still appears that the team will have a difficult time fitting a contract for Talib beneath the salary cap.

That person said the Redskins would like to sign Talib but “do not have enough cash.”

The Redskins are dealing with a tight salary cap situation as a result of the second half of their two-year, $36 million salary cap penalty imposed by the league.

The Patriots are thought to be interested in re-signing Talib.

The Redskins finished last season 30th in the NFL in pass defense and need a cornerback after releasing veteran DeAngelo Hall on Monday.

Talib was traded to the Patriots last season after spending his first four full seasons with the Buccaneers. He has 19 interceptions in his five NFL seasons. Talib was a first-round draft choice by the Buccaneers in 2008.

He was suspended by the NFL for the 2010 season opener for a violation of the league’s personal conduct policy stemming from an incident with a cab driver in 2009. He was suspended for four games last season for violating the NFL’s policy on banned performance-enhancing substances. Talib said the suspension was due to Adderall use.

He also was charged with aggravated assault with a deadly weapon after being accused of firing a gun at his sister’s boyfriend in 2011. The felony charge later was dropped.
