Gay (hamstring) returned to practice Sunday, Ryan Dunleavy of NJ.com reports.
Gay joined the Giants last week and will operate as a depth safety. He'll get some extra run while Curtis Riley (hamstring) and Darian Thompson (hamstring) are sidelined.
Gay exited Friday's practice with a right hamstring injury, Ralph Vacchiano of SportsNet New York reports.
Gay was on the sideline with his right hamstring wrapped with an ice pack. The specifics and severity of the injury for the 33-year-old are currently unclear.
Gay signed a contract with the Giants, Ryan Dunleavy of NJ Advance Media reports.
Gay played 10 of his 11 seasons in Pittsburgh, appearing in all 16 games every year of his career. His numbers took a large dip last year, with him recording just 19 tackles and three passes defensed, his worst numbers in a decade. Entering his age-33 season, he'll likely be a backup cornerback while with the Giants.
Gay is expected to be released by the Steelers on Wednesday, Jeremy Fowler of ESPN.com reports.
Gay is one of the longest tenured Steelers and was a member of the 2008 team that won Super Bowl XLIII. The 11-year vet has indicated he plans to continue playing, despite rumors of potential retirement. Gay appeared in all 16 games for Pittsburgh in 2017 but did not start any of them.
Gay, who recorded three tackles (two solo) and a forced fumble in the regular-season finale win over the Browns, finished up the 2017 regular season with 19 tackles (16 solo) with an interception and two forced fumbles in 16 games.
The 19 tackles matched his career low for a season, which he accomplished in 2007, his rookie year. Although he has never missed a game in 11 seasons, his playing time has taken a huge hit, with him taking the field for just 27.2 percent of the team's defensive snaps this season. Gay is signed until 2019, but the limited role makes him a less-than-desirable IDP fantasy option.
Gay recorded five tackles (four solo) in the Steelers' overtime win against the Browns on Sunday.
The 2016 season was almost an exact repeat of 2015 for Gay, who again finished with exactly 58 tackles, including one sack, and one interception.
Gay had an interception and totaled three tackles (all solo), including a sack in the Steelers' 28-7 win over the Colts on Thursday.
Gay sacked Indianapolis quarterback Scott Tolzien on the very first play from scrimmage, and added a fourth quarter interception to help preserve the win.
Gay (foot) will play Sunday against the Ravens.
Gay looked to have suffered an injury in practice this week, but it evidently proved to be minor in nature. Look for the veteran corner to line up in his typical spot on the outside.
Gay (foot) is questionable to play Sunday against the Ravens.
Gay went down in practice Thursday and was unable to participate Friday. Expect Justin Gilbert to get the start if he doesn't suit up.
Gay has agreed to re-sign with the Steelers on a three-year contract, the Pittsburgh Post-Gazette reports.
Gay has yet to miss a game through nine seasons and has made 70 starts over the last five years. He was Pittsburgh's only reliable cornerback in 2015, and while he'll enter 2016 at 31 years old, Gay should be locked in as a starter for the next few seasons. The cornerback position should still be a priority for Pittsburgh in the draft.
Gay recorded eight tackles (seven solo) in Pittsburgh's loss to Denver on Sunday.
Gay, who is an unrestricted free agent, finished the season with 58 tackles (46 solo), including a sack. He also had two interceptions, including one returned for a touchdown. Gay played 96.0 percent of the Steelers' defensive snaps, more than any other player on either side of the ball, while extending his consecutive regular season games played streak to 144 - the longest active consecutive games played streak among NFL cornerbacks. The Steelers should look to resign him for 2016.
Gay recorded three tackles (all solo) and an interception in Pittsburgh's win over Cleveland on Sunday.
The interception in the fourth quarter was Gay's 11th of his NFL career and the ninth as a Steeler.
Gay (not injury related) is active for Sunday's game at Baltimore.
The veteran corner will be looking to shut down the Ravens passing attack.
Gay had two tackles (one solo) and an interception for a touchdown in Pittsburgh's win over Cincinnati on Sunday.
The interception, Gay's first of the season, came on the Bengals first possession of the second half, extending the Steelers' lead to 23-7. Gay has now returned his last five interceptions over the past three seasons for touchdowns.
Gay (concussion) totaled six tackles (four solo) in Pittsburgh's win over Indianapolis on Sunday.
Gay was forced from the game and went through concussion protocol after taking a hit in the fourth quarter. If he is not cleared for the Steelers' Week 14 game against Cincinnati, it could bring an end to Gay's consecutive regular season games played streak (140), the longest active consecutive games played streak among NFL cornerbacks.
Gay totaled three tackles (one solo) including a sack in Pittsburgh's loss to Seattle on Sunday.
The sack was the first of the season for Gay, and the sixth of his career. He'll face Indianapolis in Week 13, against whom he had a team-high eight tackles and an interception return for a touchdown last season.
The Steelers released their final injury report for Week 16’s game against the Chiefs and safety Troy Polamalu (knee) is listed as doubtful.
Cornerback Ike Taylor (shoulder) is also listed as doubtful. Tight end Matt Spaeth (elbow) is the only player listed as questionable.
The following players are listed as probable: William Gay, Marcus Gilbert, James Harrison, Steve McLendon, Heath Miller, Mike Mitchell, Maurkice Pouncey, Ben Roethlisberger and Markus Wheaton.
The Steelers are 3-point favorites.
The Steelers have cleared two of their three significant probables for their Sunday game against Atlanta. Tackle Marcus Gilbert (ankle) has been ruled out. The two green-lighted are cornerback William Gay (quad) and center Maurkice Pouncey (ankle).
The Steelers have listed corner back Ike Taylor as doubtful for Sunday's game against the Falcons. Taylor, who left last week's game against the Bengals with a forearm injury, was unable to practice most of the week.
Linebacker James Harrison , who missed last week's game with a knee injury, is questionable.
The following players are probable for Pittsburgh: Ben Roethlisberger, William Gay, Marcus Gilbert, Cameron Heyward, Heath Miller and Maurkice Pouncey.
The Steelers haven't said how long starting cornerback Ike Taylor will be out due to his broken forearm, but the injury typically requires six to eight weeks to heal, reports the Pittsburgh Tribune Review. The paper expects William Gay and Antwon Blake to fill in for Taylor.
