Prior to their season opener on Monday Night Football, an internal battle took place on Saturday between a pair of playmakers for the San Francisco 49ers.

Saturday marked the latest edition of the historic rivalry game between the Iowa State Cyclones vs. the Iowa Hawkeyes. Two of the top current players from the Cyclones and Hawkeyes reside in the 49ers locker room — Brock Purdy and George Kittle.

When the Cyclones secured the 20-19 win on Saturday, Kittle had to pay the price. On Wednesday, the 49ers star tight end addressed members of the media from the locker room in Santa Clara donning a cardinal and gold Iowa State helmet, the same helmet Purdy wore for the Cyclones.

Iowa State quarterback Rocco Becht threw for 272 yards and two touchdowns along with helping set up the Cyclones' game-winning field goal. Kyle Konrardy drilled a 54-yard field goal to give Iowa State a 20-19 lead with six seconds remaining.

Iowa standout running back Kaleb Johnson rushed for 187 yards on 25 carries with two touchdowns, but it wasn't enough to save Kittle from wearing the Cyclones helmet on Wednesday in Santa Clara.
