Former Alabama rookie linebacker Mack Wilson expects to make his first career start for the Cleveland Browns this Sunday night against the Los Angeles Rams.

Wilson has been big shoes to fill, as he will be replacing linebacker and Browns defensive captain Christian Kirksey in the lineup. Kirksey may miss Sunday’s game because of a chest injury according to Ian Rapoport of NFL.com.

The Browns selected Wilson 155th overall in the fifth round of the 2019 NFL Draft. He’s played in both games this season, recording four total tackles.

At Alabama, he made second-team All-SEC in 2018, posting 65 total tackles, including 4.5 for loss and 1.0 sack with two interceptions as a junior last season. He helped the Crimson Tide win the National Championship in 2017, recording 40 total tackles, including 2.5 tackles for loss and four interceptions during his sophomore year.

It’s possible that Kirksey has a torn pectoral muscle. If that’s the case, Wilson could remain one of Cleveland’s starting linebackers for the foreseeable future.
