PHILADELPHIA -- Eagles linebacker Mychal Kendricks injured his calf Monday night. Kendricks did not practice with his teammates Wednesday. He is listed as day-to-day by the coaches.

"I've got a plan without him practicing today," defensive coordinator Bill Davis said. "We'll have the other guys get the reps."

The "other guys" are Casey Matthews, who filled in for Kendricks in Indianapolis, and Emmanuel Acho, who was signed off the practice squad last week. Najee Goode, the top backup inside linebacker, was placed on injured reserve after tearing his pectoral muscle.

"We'll see who has the better week (of practice)," Davis said. "We have complete confidence in both of them. We'll see how the week plays out, but it could be Casey or Acho, or a mix of both."

Acho is a little more dynamic, as Kendricks is. Matthews is a bit steadier and more experienced.

"There's not a whole lot of difference," Davis said. "They're both very intelligent guys who can set our front, they can line us up, they understand our defense thoroughly. They're very instinctive between the box. They're good tacklers. They're very similar skill sets -- not a whole lot of difference between the two of them."

Kendricks' injury will have an impact on veteran DeMeco Ryans, as well. Davis had been hoping to reduce Ryans' playing time a bit this year. Ryans was on the field more than any other linebacker in the NFL in 2013.

With Goode and Kendricks injured, it will be tough to take Ryans off the field. He played 71 of 73 defensive plays in the season opener against Jacksonville and was on the field for all 72 plays against the Colts.

"Those guys have to step in and pick up where Mychal left off," Ryans said. "I haven't played with them much at all. Whoever goes in, Casey or Acho, they'll have to step up and hold it down for Mychal. Those guys are pros. They'll know where to be, how to get the job done."

On the other hand, if Kendricks is able to play, the extra practice reps will help Matthews and Acho be ready to play. That could make Davis feel more comfortable having one of them spell Ryans for a series or two.
