Philadelphia coach Chip Kelly admits he didn't know injury rule in Eagles home opener

PHILADELPHIA – Chip Kelly is learning the NFL rule book on the job.

The do-it-his-way coach didn't think he could use a timeout to allow a banged-up Michael Vick to stay in the game during an important moment in the Philadelphia Eagles' 33-30 loss to San Diego Chargers to Sunday.

Upon further review, Kelly learned he was wrong.

"That's on me. I didn't think we could," Kelly said Monday. "I should have asked."

Vick got up slowly after taking a hard hit on an incomplete pass on first down from the Chargers 14. A referee told him he had to sit out one play. Nick Foles entered and threw a pass out of bounds in the end zone. Vick returned and misfired on third down, forcing the Eagles to settle for a tying field goal with 1:55 remaining.

If Kelly called the timeout, Vick could've stayed in and perhaps the second-down play would've turned out different.
