The Browns bolstered their depth at offensive tackle Friday by signing Kendall Lamm, the team announced.

Lamm received a two-year contract worth about $7 million, according to the Houston Chronicle.

Last year, Lamm started 13 games for the Houston Texans at right tackle after starter Seantrel Henderson suffered a season-ending broken ankle in Week 1. The Texans re-signed Henderson in January to a one-year, $4.5 million deal, and Lamm became an unrestricted free agent this week.

Lamm, 6-foot-5 and 310 pounds, entered the NFL in 2015 when he signed with the Texans as an undrafted free agent from Appalachian State. Since then, he has started 24 of the 55 games in which he's appeared.

Chris Hubbard is the incumbent starting right tackle of the Browns, who signed him to a five-year, $36.5 million contract a year ago.

Hubbard tied for 50th among 80 qualifying tackles last season in ProFootballFocus.com's grades. Lamm ranked 52nd.

In another O-line development, guard Earl Watford, who appeared in 13 games last season as a backup with the Browns, agreed to a one-year contract with the Tampa Bay Buccaneers, according to NFL Network.
