Philadelphia Eagles quarterback Jalen Hurts is questionable for Monday night’s game at Seattle because of an illness, a person familiar with his status told the Associated Press on Sunday.

The person, speaking on condition of anonymity because the injury report hasn’t been released yet, said Hurts will travel separately from the team.

Marcus Mariota is Hurts’ presumptive back-up should he not be able to play.

The Eagles (10-3) have lost two straight games but would secure the NFC East title if they beat the Seahawks (6-7) and win their final three games.

Additionally, Matt Patricia is replacing Sean Desai as the defensive play-caller for Philadelphia, multiple sources reported on Sunday.

Desai will continue his role as defensive coordinator but is moving to the booth, according to the person who spoke to the AP on condition of anonymity because the team hasn’t announced the switch.

Patricia, a three-time Super Bowl champion as a defensive coach with the New England Patriots and a former head coach with the Detroit Lions, joined the Eagles as a senior defensive assistant this year after Desai replaced Jonathan Gannon as the defensive coordinator.

The Eagles have allowed 109 points over the past three games.
