"One of our goals," said CEO Joe Banner, "is whenever possible to develop and keep our own players. We're glad in this case that it worked out, and was mutually beneficial."
"John is a solid, all-around teammate, on and off the field," said Head Coach Rob Chudzinski. "He was given an opportunity to play last year and really showed well. He's respected in the locker room for his approach, consistency and team-first attitude."
Greco, a 6-4, 315-pound veteran in his sixth NFL season out of Toledo, is now signed through the 2017 season. He has seen action in 55 career contests with 14 starts.
In 2012, he appeared in 14 games, including a career-high 10 starts, all at left guard. Last season, the Youngstown, Ohio, native was a part of an offensive line that helped pave the way for Trent Richardson, who rushed for a 950 yards, and protected for Brandon Weeden, who threw for 3,385 yards, both franchise records among rookies.
Originally selected by St. Louis in the third round (65th overall) of the 2008 draft, Greco was traded to Cleveland prior to the start of the 2011 season.
The Cleveland Browns on Tuesday signed free agent Naaman Roosevelt, the club announced.
Roosevelt, a 6-0, 200-pound wide receiver in his third NFL season out of the University at Buffalo, has appeared in 16 NFL games, all with the Buffalo Bills. His first name is pronounced NAY-man.
An undrafted free agent, Roosevelt initially signed with the Bills in 2010 and has recorded 25 career receptions for 396 yards with one touchdown. He set career highs in 2011 after appearing in 10 games with 16 receptions for 257 yards with one touchdown. He spent training camp with the Bills last season.
While in college, Roosevelt set school records in receptions (268), receiving yards (3,551), touchdown catches (28) and all-purpose yards (5,341). A native of Buffalo, N.Y., he graduated from the city's St. Joseph's High School.
