SANTA CLARA – Kenneith Acker will be back in the starting lineup Sunday against the Arizona Cardinals after sitting out the second half in last week’s game.
San Francisco 49ers defensive coordinator Eric Mangini said Acker will start but Marcus Cromartie will also see plenty of action at right cornerback -- just as they did a week earlier in the 49ers’ 29-13 loss Sunday against the Seattle Seahawks.
“Acker will start, but Cro will play and I think that’s a good combination,” Mangini said on Friday. “I think when Marcus came in last game he did a good job. I’ve been really happy for him, proud of him. Love his approach. Love the way that he’s earned more opportunities and when he gets the chance to go in, the way that he approaches everything.”
With Acker making his ninth start of the season (he sat out the Nov. 8 game against the Atlanta Falcons with a concussion), the Seahawks got out to a 20-0 lead. Acker was in coverage on Russell Wilson’s 11-yard touchdown pass to Tyler Lockett in the second quarter.
In the second half, Cromartie, who started and played well against the Falcons two weeks earlier after his promotion from the practice squad, took over at cornerback. But Mangini said that was the plan all along. Cromartie gave up one reception for 8 yards in the second half, according to Pro Football Focus.
“No matter what the situation in the game was, Marcus was going to get an opportunity to play,” Mangini said. “So it wasn’t that specific chain of events. But he was going to get the chance to play. And, remember, Ack was coming off the injury, so it was going to work out that way either way.”
