Greenway didn't practice all week. Coach Mike Zimmer said he probably could have participated Friday, but the team didn't want to risk aggravation.
Greenway's backup, Brandon Watts, was ruled out with a hamstring injury. The starter at the other outside spot, Anthony Barr, is also out with a knee injury. That leaves only Jasper Brinkley, Gerald Hodges and Audie Cole as healthy linebackers on the roster, plus two practice-squad players that Zimmer said are possibilities for promotion for the game Sunday against Chicago.
