According to a report from Howard Eskin, Philadelphia Eagles starting inside linebacker Mychal Kendricks will not play on Sunday against the Washington Redskins.

Chip Kelly made clear @eagles LB Mychal Kendricks would not practice 2day but left sunday unclear. However I'm hearing he will b out Sunday — Howard Eskin (@howardeskin) September 18, 2014

Kendricks suffered a calf injury against the Indianapolis Colts on Monday night. The starting linebacker was forced to leave the game early and would not return.

The Eagles haven't announced an official decision on Kendricks yet. In the meantime, Kendricks missed practice on Wednesday and he is sitting out again on Thursday. Prior to Thursday's practice, head coach Chip Kelly noted that Kendricks is still "day-to-day", which is how defensive coordinator Bill Davis described Kendricks on Wednesday. Kelly also added that Kendricks "might" practice on Friday.

If Kendricks can't play, it certainly wouldn't be good for Philadelphia. The Eagles are already thin at inside linebacker due to a season-ending pectoral injury suffered in Week 1 by top backup linebacker Najee Goode. The much-maligned Casey Matthews or Emmanuel Acho may have to start in place on Kendricks. It's worth noting the Eagles are also cross-training rookie first round pick outside linebacker Marcus Smith II to play on the inside as well.

UPDATE (3:11 PM EST) - NJ.com is now confirming Eskin's report and adding on that Kendricks also might not play in Week 4 against the San Francisco 49ers.
