Seneca Wallace has said that he plans to retire from playing in the NFL, according to reports.
The San Francisco 49ers quarterback did not play during the team's 41-6 win over the San Diego Chargers last night.
The Sacramento Bee reports that the 33-year-old told head coach Jim Harbaugh that he no longer plans to play.
Harbaugh added that he had "never seen that on a game day".
Wallace joined the 49ers last week after being released by the New Orleans Saints.
