49ers' Dre Greenlaw: Misses practice

Greenlaw (back) was a non-participant at Wednesday's practice.

Greenlaw exited the 49ers' previous game against Las Vegas early after injuring his back. His non participation Tuesday is not a good start to the week, so his status will need to be monitored going forward. Oren Burks would be the prime candidate to replace him at weakside linebacker if he ultimately has to miss any time
