Los Angeles Chargers running back Austin Ekeler is believed to have suffered a hyperextended knee and hamstring injury on Sunday that is expected to keep him out several weeks, a source told ESPN's Adam Schefter.
Ekeler was seen leaving Sunday's game at the Tampa Bay Buccaneers on crutches and with a brace, according to Schefter. He is expected to undergo an MRI on Monday.
He had 12 yards on two carries and one reception for 2 yards before leaving with 1:37 left in the first quarter of Los Angeles' 38-31 loss. He leads the Chargers with 248 rushing yards and is third on the team with 144 receiving yards this season.
Ekeler, 25, signed a four-year, $24.5 million extension with the Chargers in the offseason. After a lengthy contract dispute with Melvin Gordon, Los Angeles signed Ekeler long term instead.
Gordon eventually signed with the Denver Broncos, clearing the way for Ekeler to be the Chargers' featured back.
