Ndamukong Suh is taking his talents to South Beach.

Barring any unexpected snags in contract negotiations, the coveted defensive tackle will join the Dolphins once the free-agency signing period begins Tuesday afternoon.

ESPN reported Sunday that Suh had agreed to a deal worth about $114 million over six years, including $60 million guaranteed. The news comes after persistent speculation that Miami had become the front-runner to sign him.

Suh's contract is the richest ever for a defensive player, surpassing the six-year, $100-million deal that Texans All-Pro lineman J.J. Watt signed last year.

Teams were permitted to begin negotiating with free agents Saturday, and it didn't take long for Suh's agent, Jimmy Sexton, to swing a deal.

The move continues a stunning series of developments in the AFC East. The Bills traded for Eagles running back LeSean McCoy, who agreed to a new five-year, $40-million contract Sunday, and the Jets traded for Bears receiver Brandon Marshall. The Bills also traded for Vikings quarterback Matt Cassel -- and former Jets general manager Mike Tannenbaum, now the lead football executive in Miami, answered with his own megadeal for Suh.

In other free-agent developments Sunday, the Eagles appear to have settled on 49ers free agent Frank Gore as McCoy's replacement and also are expected to sign Seahawks free-agent cornerback Byron Maxwell, according to ESPN. A source confirmed that former Jets quarterback Mark Sanchez is returning to the Eagles after agreeing to a two-year deal worth a maximum of $16 million.

Gore, who'll be 32 in May, has run for more than 1,000 yards nine times. Maxwell, 27, was part of the Seahawks' "Legion of Boom" secondary and had six interceptions the last two seasons.

Suh, 28, leads all tackles with 36 sacks since his rookie season of 2010, including 81/2 in 2014.

He doesn't come to the Dolphins without any risk. He was suspended for two games in 2011 for stomping on a Packers lineman and initially was suspended for the Lions' playoff game against the Cowboys last season for stepping on Packers quarterback Aaron Rodgers' leg. Suh appealed and was allowed to play.
