The self-proclaimed best right tackle in the NFL is out of a job. The Giants are waiving Bobby Hart, according to multiple people familiar with the situation. The news was first reported by NorthJersey.com.

Former Giants offensive lineman Geoff Schwartz tweeted that Hart "came into the facility and told the staff he wasn't playing this week." Hart responded in a since-deleted tweet, "Schwartz you quit on the team my rookie year after you secured your guaranteed money bro. Maybe i learned shutting down from you lol."

Hart had been listed as questionable for Sunday's game against the Redskins after being a limited participant in practice all week with an ankle injury.

New general manager Dave Gettleman clearly isn't wasting any time getting to work on his plan to rebuild the Giants' offensive line. And getting rid of Hart also is a first step in Gettleman's efforts to clean up the locker room.

Hart started 20 games over the past two seasons at right tackle despite subpar performance. Hart infamously told NJ Advance Media before the season, "I know I'm the best right tackle in the league."

Hart is graded 82nd out of 87 tackles this season, according to Pro Football Focus. He graded as the 67th-best tackle in the league last season.

Sixth-round pick Adam Bisnowaty, who has spent the entire season on the practice squad, will be promoted to the active roster and will start at right tackle on Sunday, according to a person familiar with the situation. Rookie Chad Wheeler will make his first career start at left tackle in place of Ereck Flowers, who was listed as questionable with a groin injury, according to a person familiar with the situation.

Hart was due $705,000 next season in the final year of his rookie contract. He was actually in line to collect a bonus worth approximately $1 million because he's a seventh-round pick who had played more than 35 percent of the Giants' offensive snaps in the past two seasons.

The Giants have also promoted offensive lineman Nick Becton and tight end Ryan O'Malley from the active roster. And they put wide receiver Tavarres King, who suffered a concussion in Week 15, on injured reserve.
