San Francisco 49ers linebacker Ahmad Brooks, who did not seem to take a liking to the reduction in his playing time caused by Aldon Smith's return to the lineup, illustrated his displeasure by taking himself out of Sunday's 16-10 win over the New York Giants, according to multiple media reports.
Brooks did not play in the second half and played only the first two-plus series. He confirmed after the game that he is healthy.
"We're working through something," Niners coach Jim Harbaugh said.
At his locker after the game, Brooks declined to comment on his situation.
"I'm not taking questions today," he said. "Maybe later in the week. ... Yeah, we're working through something."
Brooks started over Smith on Sunday but saw much of his playing time split. Also getting plays in the nickel package was Aaron Lynch.
"Honestly, I don't know what happened there," Lynch told reporters when asked about Brooks. "I don't know what the deal was. I love the guy. He's a big brother to me. As far as what happened off the field or on the field, I don't know what happened."
Brooks was previously at the center of a trade rumor that had him going to Cleveland last month. Still, Harbaugh indicated Brooks' roster spot was safe.
"We need Ahmad Brooks to win a championship," he said.
