The Browns are expected to sign veteran offensive tackle Chris Hubbard to a five-year contract, a person familiar with the move confirmed Tuesday.

The deal is worth approximately $37.5 million, including $18 million guaranteed, the source said. NFL Network first reported the news.

Hubbard, 26, cannot sign the contract until free agency officially opens at 4 p.m. Wednesday.

Hubbard started 14 of the 39 regular-season games in which he appeared the past four years with the Pittsburgh Steelers. His primary position is right tackle. He appeared in all 16 games last season and started 10 of them, all at right tackle.

Whether Hubbard, 6-foot-4 and 295 pounds, stays at right tackle could hinge on the decision Browns 10-time Pro Bowl left tackle Joe Thomas makes about his future, so the situation is fluid. Thomas has yet to announce whether he'll return for another season or retire.

Hubbard is known for his versatility and played both tackle and both guard spots during his time with the Steelers. The Boston Globe, citing a source, reported Tuesday the Browns are also “making a big run” at New England Patriots left tackle Nate Solder.

Right tackle Shon Coleman, a third-round draft pick in 2016, started all 16 games for the Browns last season during his first year as a full-time NFL starter. Coleman, 26, played left tackle during his entire career at Auburn and would relish an opportunity to move there for the Browns.

New Browns offensive coordinator Todd Haley held the same position with the Steelers throughout Hubbard's tenure in Pittsburgh. Hubbard joined the Steelers as an undrafted free agent from Alabama-Birmingham in 2013.

The Browns also agreed to a one-year, $2.5 million contract with veteran offensive tackle Donald Stephenson, 29, another source confirmed Tuesday.

Stephenson, 6-foot-6 and 312 pounds, has experience playing left and right tackle. He has started 37 of the 80 regular-season games in which he has appeared. He started four of the seven games he played last season for the Denver Broncos.
