NEW YORK — Josh Allen and Ryan Fitzpatrick are all questionable to play Sunday, according to the Colts.
Allen missed practice on Monday with a concussion and has not practiced since.
He is expected to miss a second straight game with the concussion.
Facing the Eagles at MetLife Stadium, the Eagles are 7-1.
Fitzpatrick has missed a month with a knee injury.
He practiced on Monday and said Tuesday he felt good.
The Eagles are 2-3, but have been outscored by 23 points in their last three games.
They are on pace for their worst start in franchise history, trailing only the 1999 team that was 10-5.
The Colts will be without starting quarterback Andrew Luck (ankle) and ailing running back Frank Gore (hamstring), who is questionable to return.
They have allowed five or more touchdowns in four of their last five games.
Gore is one of just five players in the NFL to have at least 1,000 yards rushing.
Luck, who has averaged more than 2,000 passing yards per season, has averaged 2,066 yards in five games, his best streak since 2006.
The last Colts player to eclipse 1,100 rushing yards was Ray Lewis in 2010.
Allen is tied for the league lead with 14 touchdown passes.
The Chargers are 2 for 2 in games decided by two points or less.
This is the fifth time in five weeks the Colts have been without an official practice.
If the Colts are unable to play on Sunday, the team will continue with the Thursday night practice.
