The Jets signed former Atlanta Falcons defensive back Robenson Therezie after safety Doug Middleton reportedly suffered a torn pec.
Therezie, a 26-year-old free safety, recorded one interception, two passes defensed and 36 combined tackles in 25 games with Atlanta over the past two seasons. He was an undrafted free agent out of Auburn.
Middleton, who was competing for a backup role with New York, recorded six combined tackles and one pass defensed in four games as a Jet last season. He suffered the injury in the fourth quarter in Saturday's 7-3 preseason win over the Tennessee Titans and is expected to undergo surgery, according to the New York Daily News' Manish Mehta.
The Jets also announced they waived fullback Algernon Brown, who appeared in eight offensive plays and two plays on special teams on Saturday. He recorded 1,310 rushing yards and 13 rushing touchdowns in four seasons with BYU.
