Kansas City Chiefs rookie running back Clyde Edwards-Helaire is expected to miss the rest of the regular season with a high ankle sprain and a strained hip, ESPN reported Monday.

The first-round pick from LSU sustained the injuries during the Chiefs’ 32-29 victory Sunday in New Orleans.

He exited the game in the fourth quarter and could not put weight on his left leg as the team’s medical staff helped him off the field. He finished with 14 carries for 79 yards and one reception for 4 yards.

The injury happened at the end of a 4-yard run by Edwards-Helaire, who was bent backward while being tackled.

The 21-year-old newcomer leads the Chiefs (13-1) with 803 rushing yards and four touchdowns in 13 games. He also has caught 36 passes for 297 yards and one touchdown.

Kansas City is hopeful Edwards-Helaire can return for the postseason, according to the report. In the meantime, the Chiefs will turn to Le’Veon Bell to carry the load for their final two regular-season games against the Atlanta Falcons and Los Angeles Chargers.

Bell, who was released by the New York Jets on Oct. 14, made his Kansas City debut in Week 7. He rushed 15 times for 62 yards and one touchdown against the Saints.
