San Francisco 49ers placekicker David Akers says he received death threats on Twitter and has closed the account.
Akers says the threats came last week. Once he saw them, he reported it to team and NFL security personnel.
He also reveals Thursday that he underwent double hernia surgery last February following his All-Pro season. Akers went to see the same doctor in Philadelphia this season to have injections.
Unlike 2011, when he made 44 of 52 field goals, Akers has been in a slump this season. He is 29 for 42 on field goals.
