Acker started alongside Tramaine Brock in Monday's win over Minnesota.

EDGE Analysis

Acker apparently has won the competition for the number two spot on the 49ers' depth chart over Dontae Johnson. He finished with four tackles (three solo) in the win.

Acker missed the entire 2014 with a stress fracture in his left foot. If Acker rehabs well in the offseason, he will compete for roster spot in training camp. If he makes the squad, he would likely serve a depth role in 2015.

Acker will miss the season with a stress fracture in his left foot, the Sacramento Bee reports. Acker was placed on season-ending IR during the roster cuts last week, and the foot injury was the culprit. It was reported that he was playing in the 49ers' last two preseason games with the injury, which he was unaware of until team trainers pointed it out to him. He will spend 2014 recovering from the injury and hopes to earn his spot with the team next season.

Acker looked strong in Sunday's preseason game against the Broncos. The 2014 sixth-round pick recorded a tackle, deflected a pass, and drew an offensive pass interference penalty in the loss to the Broncos. He is currently buried on the depth chart and may end up on the practice squad, but a strong showing in the 49ers' final two preseason games may earn him a spot on the 53-man roster.

49ers signed sixth-round CB Kenneth Acker to a four-year contract. A three-year starter at SMU, Acker had 159 tackles, 29 pass deflections, and seven interceptions during his college career. He's a long shot to make the 49ers' final roster, but is a candidate for the practice squad.
