Kerr will provide the Bengals with depth on the defensive line with Larry Ogunjobi (foot) done for the postseason. Kerr is 31 years old and is a rotational lineman. He should help the Bengals fill snaps along the line.

The 30-year-old was cut by the Panthers last week. Kerr is a pure rotational lineman who will soak up some snaps along the Niners' defensive line. He has 9.5 sacks in 88 career games. 

The move saves the team $1.3 million in cap space. Kerr, signed to a two-year deal last offseason, totaled two sacks and 32 tackles as a rotational piece across 390 (37%) defensive snaps. He'll land elsewhere on a one-year deal as a viable veteran lineman.

The 29-year-old pickup would normally be viewed as a depth piece, but the losses of Gerald McCoy and Dontari Poe in the open market could force Kerr into an important role early. He totaled 19 tackles in Arizona last year, soaking up 328 defensive snaps across 12 appearances off their bench.
