Los Angeles Chargers running back J.K. Dobbins suffered a sprained MCL and is expected to be out Sunday against the Atlanta Falcons, a source told ESPN’s Adam Schefter on Wednesday.

Dobbins will be week-to-week moving forward, the source told Schefter.

Dobbins sustained his injury in the first half of the Chargers’ 30-23 loss Monday night to his former team, the Baltimore Ravens, and didn’t play in the second half. He had 40 yards on six carries before the injury.

He ranks fourth in the AFC in rushing (12th in the NFL) with 766 yards, averaging 4.8 yards per carry, and has scored eight rushing touchdowns. He has been considered among the contenders for Comeback Player of the Year after sustaining a torn Achilles tendon in last season’s opener.

With Dobbins sidelined, running back Gus Edwards will likely get the bulk of the carries against the Falcons.

The Chargers (7-4) are in second place in the AFC West.
