The Chicago Bears and free agent tight end Martellus Bennett agreed to terms on a four-year deal.
The Bears confirmed at 6 p.m. ET the two sides had an agreement in a press release Tuesday.
Bennett said two hours earlier via Twitter that he would be joining good friend Brandon Marshall.
"I'm proud to say I'll be joining my brother @bmarshall next season," Bennett wrote. "No deal done. Just know that's where I wanna be."
Bennett parlayed his breakout season with the Giants -- 16 starts, 55 receptions for 626 yards and five touchdowns -- into strong interest in free agency.
The 26-year-old was a second-round pick of the Dallas Cowboys in 2008, but played sparingly as Jason Witten's backup.
Chicago's tight end production was a sore spot for general manager Phil Emery. Kellen Davis started for the Bears last season but was primarily a blocker. He had 19 receptions, but was the intended target on 44 pass plays.
Bennett, at 6-5, 265, has the speed to challenge safeties down the middle of the field and the size to effectively block.
