FILE - Buffalo Bills quarterback Josh Allen (17) talks with Baltimore Ravens quarterback Lamar Jackson (8) following a 24-17 Ravens win in an NFL football game in Orchard Park, N.Y., in this Sunday, Dec. 8, 2019, file photo.
It happened in the 2018 season opener, when the then-raw rookie Bills quarterback was shoved into the Ravens' sideline.
Much like Jackson, Allen prefers putting the past behind him and focusing on the next challenge.
“We’ve had our backs against the wall since the Pittsburgh game,” Harbaugh said.
The Bills limited the Ravens to only 118 yards rushing in last year’s meeting, a 24-17 Ravens win.
