Green Bay running back Eddie Lacy had one carry for 10 yards about two minutes into Sunday’s game against the Redskins . . . and then he was done for the day.
The play ended with Lacy's concussion on a helmet-to-helmet collision with Redskins safety Brandon Meriweather. (Meriweather would exit the game early in the second quarter with a concussion of his own.) As is generally the case with concussions, there is no predicting a recovery timetable because each injury is different.
As any lingering at-rest concussion-related symptoms clear, Lacy will gradually be introduced to increasing physical and cognitive activity, a rehab program of sorts for the brain’s response to stimulation following a concussion.
Each team has its own program, but generally the plan involves introducing light cardiovascular work and cognitive tasks (such as quiet reading), followed by more aggressive football-related drills and advanced cognitive demands (such as watching film, participating in meetings).
In order to return to play, however, Lacy will have to meet the NFL league guidelines. He will have to be free of symptoms both at rest and with exertion; his neurocognitive (ImPACT) tests will need to return to baseline; and he will need to be cleared by both team physicians and an independent neurological consultant.
Depending on the severity of his symptoms, it’s possible a decision on his status could remain undetermined until late in the week.
