HENDERSON, Nev. -- Las Vegas Raiders starting left tackle Kolton Miller sustained a high ankle sprain and a hairline fracture in Sunday's 25-24 loss to the Chicago Bears , a source confirmed to ESPN.

He's expected to be placed on the injured reserve list.

Miller was injured during the 48-second mark of the fourth quarter when Bears defensive end Tanoh Kpassagnon dove into him while attempting to tackle running back Ashton Jeanty .

Miller was looked at by trainers on the field and then carted into the locker room. The eight-year veteran was seen walking with crunches after the game.

Miller's injury came on an afternoon in which the offensive line put together its best performance of the season. The unit allowed just three pressures after giving up 51 in the first three games.
