Josh Allen injury impact: Three biggest ways Bills offense will change if Case Keenum starts at quarterback

Keenum would start Sunday vs. the Vikings if Allen can't play due to an elbow injury

Bills quarterback Josh Allen missed practice on Thursday and got in a limited session Friday as he deals with a right elbow injury to the ulnar collateral ligament and related nerves. He's listed as questionable for Week 10, and veteran backup Case Keenum would start on Sunday against the Minnesota Vikings if he's unable to go.  Peyton Manning (2013) 2,893 Andrew Luck (2014) 2,855 Lamar Jackson (2021) 2,809 Russell Wilson (2020) 2,806 Josh Allen (2022) 2,795 Less than 10 air yards 70% 71% 11-20 air yards 61% 55% 21+ air yards 32% 35% Completion percentage 70% 68% Yards per attempt 8.8 9.0 Passer rating 109.2 115.0

There's no replacing Allen if he misses any stretch of time. He's been the MVP favorite for most of the season and epitomizes the phrase "one man band" better than anyone else in the league right now. He leads the Bills in rushing and has racked up the fifth-most total yards (passing and rushing) by any player through eight games since the 1970 AFL-NFL merger. He's accounted for 23 of the Bills' 25 touchdowns this season, the highest rate (92%) in the NFL. 

Below is a look at the most total yards (pass and rush) through eight games -- since 1970.
