Broncos rookie running back Jonah Coleman scored his first NFL touchdown in Week 2, but he won’t have a chance to add to that total for a while.

The Broncos placed Coleman on injured reserve Saturday. He had been ruled out for Sunday’s game against the Rams on Friday and will now have to miss at least four games.

Coleman was pressed into duty with J.K. Dobbins and RJ Harvey sidelined last weekend, but both backs are set to play on Sunday night.

The Broncos signed long snapper Mitchell Fraboni to the 53-man roster in a corresponding move. Fullback Adam Prentice and wide receiver Kolbe Katsis have been elevated from the practice squad and will revert back after facing the Rams.
