The Buffalo Bills have officially listed quarterback Josh Allen as questionable for Sunday's key game against the Minnesota Vikings as the midseason MVP candidate continues to manage a sprained right elbow.
Allen was termed a limited participant in Friday's practice after sitting out the previous two days with an injury he picked up in Buffalo's 20-17 loss to the New York Jets last weekend.
The five-year veteran did not leave that contest but had his most ineffective performance of the season, completing just 18 of 34 passes for 205 yards with no touchdowns, two interceptions and a 46.8 passer rating.
"We are literally in an hour-to-hour situation here," Bills coach Sean McDermott said of Allen on Friday.
"We're just looking at how he's going to progress through the day, and as he goes through these different tests, medically, making sure he's able to check the boxes in a progression to where we can see if we can proceed through the course of the day here."
McDermott was then asked what Allen will need to show the coaching staff in order to be cleared for the clash against the 7-1 Vikings.
"That's probably getting too far down the road at this point or into the weeds."
If Allen ends up inactive, journeyman Case Keenum would direct a Bills offense that ranks second in the NFL in total yards per game.
Keenum made a pair of starts for the Cleveland Browns in 2021 and won both while compiling 375 passing yards with three touchdowns, one interception and a 95.3 rating.
Allen sat out four games with a similar issue in his elbow as a rookie in 2018 but has not missed a game since, having started Buffalo's past 69 games including the postseason.
