Bears waive backup receiver Ihmir Smith-Marsette

LAKE FOREST, Ill. - The Chicago Bears waived receiver Ihmir Smith-Marsette on Tuesday.

Smith-Marsette got his first significant playing time in the offense in Chicago's 29-22 loss at Minnesota two weeks ago and committed two costly mistakes.

He had the ball taken away from behind by Cameron Dantzler at the Vikings 39 following a reception on the Bears’ final drive to decide the game. He also got flagged for an illegal block from behind on a 52-yard scramble by quarterback Justin Fields, negating a touchdown. The Bears signed Smith-Marsette just before the start of the season after Minnesota cut him.
