Fields is likely on his way to returning on Monday.He completed 16 of 22 passes for 218 yards and one touchdown in the season opener loss to the Pittsburgh Steelers on Sept. 7. Fields went of 11 before going down following a hit from Joey Bosa in the Week 2 game against the Buffalo Bills.The quarterback missed the Week 3 matchup with the Tampa Bay Buccaneers and is still in the NFL's concussion protocol.

I know what you're trying to ask, but we'll make sure we talk about that as a staff, first and foremost.”Glenn added that Fields came as their starter, and it has been the case all along. The coach avoided making any statement about his quarterback without getting a clear picture. He added that Tyrod Taylor is just a backup and hinted that Fields will be back in action as soon as he is fit.Taylor went 7 of 11 for 56 yards and one touchdown in the 30-10 loss to the Bills. He completed 26 of 36 passes for 197 yards, two touchdowns and one interception in the 29-27 defeat to the Tampa Bay Buccaneers on Sunday.New York badly needs a win, and Fields will be crucial for the team as they still look to make the postseason.
