Falcons' Keanu Neal: Out 3-4 weeks

Updating a previous note, Neal will undergo knee surgery on Monday, keeping him on the sidelines for the next 3-to-4 weeks, Adam Schefter of ESPN.com reports.

Analysis:

Neal injured his knee in the first quarter of Thursday night's preseason loss to the Dolphins as he attempted to tackle a free-running Arian Foster. The injury is minor, but requires a procedure that will likely keep the rookie off the field for the first game of the season. In the meantime, expect Kemal Ishmael and Damian Parms to see increased workloads.
