Ezekiel Elliott didn't participate in practice Tuesday or Wednesday after he suffered a head injury in a "minor car accident" on Sunday night, the Dallas Cowboys announced.

Elliott worked off to the side of practice Wednesday as a precaution. Jason Garrett said the running back would also sit out on Thursday before returning to the field on Tuesday.

He was the passenger in a car that was rear-ended on Sunday night.

Keenan Allen has returned to the practice field ahead of schedule after tearing his ACL eight months ago.

Allen described himself as "80 to 85 percent" healthy in April.

"We've been real cautious with him," Los Angeles Chargers coach Anthony Lynn said. "We're just working him in right now on a limited basis. But he's full go."

Allen has appeared in just nine games the last two seasons, losing half of his 2015 campaign to a lacerated kidney.

Doug Martin was involved in a car crash in Tampa on Thursday.

At approximately 1:15 p.m., Martin's black BMW was struck by a black Kia in the middle of an intersection, resulting in the Kia ramming into the side of a periodontist's office and destroying an air conditioning unit.

Police say Martin suffered minor cuts and bruises from the crash. 

The Bucs released a statement Thursday afternoon that said Martin has been evaluated by the team's medical staff and has headed home.
