Raiders’ starting left tackle goes on injured reserve

The Raiders put starting left tackle Kolton Miller on injured reserve Tuesday.

Miller was carted off the field late in the fourth quarter of Sunday’s 25-24 loss to the Chicago Bears at Allegiant Stadium. Tests revealed a right high ankle sprain and a hairline fracture in the ankle.

A timeline for Miller’s return was not clear, but the transaction means he will miss at least four games, starting with Sunday’s at Indianapolis.

It’s a crushing loss for the Raiders to lose Miller, the fourth-ranked offensive tackle in the NFL this season, according to Pro Football Focus.

Miller, a first-round draft pick in 2018, signed a three-year, $66 million contract extension with $42.5 million guaranteed in July.

Coach Pete Carroll said Monday that Stone Forsythe would get the first opportunity to replace Miller in the starting lineup. Rookie Charles Grant also could be in the mix to see his first action.

“He’s capable of playing,” Carroll said of Grant. “He’s done really well for us, but we’ll look after him in giving him his opportunity to start. Stone’s played a lot of football and has done a nice job for us since he’s been here, and he would be the first choice, but this is an opportunity for Charles to make a charge for it, and we’ll see how he does.”

In corresponding moves, the Raiders signed tight end Carter Runyon to the active roster from the practice squad and signed free agent offensive tackle Leroy Watson IV to the practice squad.
