Cornerback Darrelle Revis and the New England Patriots have reached agreement on a contract, according to league sources.

While Revis' deal has a cash value of $12 million this year, as reported by ESPN, the sides added a second year to the pact. The second year is worth $20 million, a sum so large it makes it unlikely the Patriots would pay it, thus making Revis an unrestricted free agent again in 2015.

The second year helps the team spread the salary-cap charges for Revis over two seasons instead of taking one $12 million cap hit in 2014. It also eliminates the chance he could be given the franchise tag by the Patriots in 2015.

Revis still needs to pass a physical and sign his contract. Once he does, it will continue Revis' reign as the NFL's highest-paid cornerback and give the Patriots the player they needed to replace cornerback Aqib Talib, who unexpectedly bolted for the Denver Broncos on Tuesday.

Once Tampa Bay released Revis on Wednesday, New England immediately stepped up its pursuit. The sides quickly were able to come together to reach the one-year agreement that again will give the cornerback an opportunity to hit the free-agent market after the 2014 season and become one of the biggest stories of next March.

The Buccaneers released the five-time Pro Bowl cornerback after being unable to trade him and his $16 million salary. The move saved the team a $1.5 million bonus that Revis would have been due if he remained on the roster.

The Patriots might not be done fortifying the roster at cornerback. Free agent Brandon Browner is scheduled to visit with team officials, a league source confirmed to ESPNBoston.com's Field Yates. Browner is suspended for the first four games of the 2014 regular season, after sitting out the final five games of last season for a violation of the league's substance-abuse policy.
