The Chicago Bears went toe-to-toe with the Minnesota Vikings on Sunday, but a mistake by former Iowa WR Ihmir Smith-Marsette ultimately cost the Bears a chance to tie the game late.

Down 22-29 with 1:08 left on the clock in the 4th quarter, Smith-Marsette caught a pass from QB Justin Fields, turned, and took off down the field. The WR faced a wall of three Vikings defenders in the front, with one approaching from behind.

Smith-Marsette failed to secure the ball, and the Viking defender was easily able to approach from behind and strip the ball, sealing the win for the Vikings.

Watch the disastrous play below:

As a freshman at Iowa, Smith-Marsette had 187 yards and 2 touchdowns. During his junior year, Smith-Marsette caught 44 passes for 722 yards and 5 touchdowns while also rushing for 108 yards and 3 touchdowns. He also returned 17 kickoffs for 503 yards and 2 touchdowns in his junior year.

Smith-Marsette was drafted by the Minnesota Vikings in the fifth round, of the 2021 NFL Draft before being claimed off waivers by the Bears last month.
