TEMPE, Ariz. (AP) - Arizona coach Bruce Arians says the availability of running back Andre Ellington on Sunday at Philadelphia will be ''a game-time decision.''
Ellington injured his left knee late in practice on Thursday and sat out Friday's workout.
The loss of the dynamic rookie from Clemson would be a significant blow to the Arizona offense, because he provides speed that the team's other backs don't possess.
Although he didn't carry the ball at all in the season opener, Ellington leads the Cardinals in rushing with 441 yards on only 73 carries, an average of 6 yards per carry. He also has 28 receptions for 247 yards.
