It looks increasingly unlikely Arizona Cardinals running back Andre Ellington will play in the team's Monday night's game against the San Diego Chargers, according to ESPN's Adam Schefter and Chris Mortensen (via Rotoworld).

Schefter and Mortensen are getting a "negative vibe" around Ellington.

"The vibe we're getting is negative," said Schefter. "We'd be surprised to see him out there Monday night."

Ellington is battling a foot injury sustained this past week that came as a surprise to many. Doctors told him earlier this week he would not need surgery on his foot, and Ellington did practice on Saturday.

Cardinals mum on severity of Ellington injury

The ESPN report comes one day after Cardinals head coach Bruce Arians told AZCentral.com there was "no doubt" Ellington would play Monday.

The second-year player out of Clemson, who rushed for 652 yards and four touchdowns on 118 attempts last season, is expected to take on a more significant role in the Cardinals offense this season. Ellington is listed as the Cardinals' starting running back, ahead of Jonathan Dwyer, Stepfan Taylor and Robert Hughes.
