Philadelphia Eagles running back Chris Polk had surgery on his shoulder this week, according to a report from ESPN’s Adam Caplan.

That is worth noting, but bears further exploring because of what it says about the way the Eagles handle injuries in the Chip Kelly era.

Andy Reid famously began every press availability with the same word -- injuries -- followed by an alphabetical recitation of every nick, ding, tear, pull and break on the athletic trainers’ report. For serious injuries, especially when star players were involved, Reid brought head trainer Rick Burkholder in to explain the nature of the injury and the course of treatment.

With Kelly?

“Polk has got a shoulder,” he said Oct. 14, the day after Polk was injured in Tampa. “We hope he’s back this week, but I don’t think he’ll be full [go in practice] tomorrow.”

That was all the information Kelly was giving out, which was typical. An injured player has a (fill in body part here). Period. Kelly says he doesn’t want or need in-depth information. The training staff tells him who is available and who isn’t and he proceeds from there.

Polk was inactive for the following week's game against Dallas. Not that big of a deal, except for the roster consequences that followed. The day before the Dallas game, the Eagles added practice squad running back Matthew Tucker to their active roster. To make room, they released cornerback Jordan Poyer, a seventh-round pick in the 2013 draft.

The Cleveland Browns claimed Poyer and he finished the season with them.

Polk was back the following week and active for the rest of the Eagles’ games. He played extensively on special teams. His snap count on offense increased in the final four weeks.
