Allen (coach's decision) is inactive for San Francisco's game against the Vikings on Monday, Matt Barrows of The Athletic reports.

EDGE Analysis

Allen will serve as the team's emergency third quarterback and will be eligible to play only if both Brock Purdy and Sam Darnold both suffer injuries. The 31-year-old last played in a game for the Bengals last season where he completed all three of his passes for 22 yards.
