Tyrod Taylor's expected departure from the Browns will become official soon, with NFL Network reporting Wednesday the veteran quarterback has agreed to a two-year contract with the Los Angeles Chargers.

Deals cannot be finalized until free agency begins at 4 p.m. Wednesday. Taylor would back up Chargers eight-time Pro Bowl quarterback Philip Rivers.

A year ago, Browns General Manager John Dorsey traded a third-round draft pick to the Buffalo Bills for Taylor so he could enter the season as the starter before eventually passing the torch to Baker Mayfield, the No. 1 overall pick in last year's draft.

The changing of the guard happened sooner than the Browns had planned.

Taylor, 29, suffered a concussion in Week 3 against the New York Jets. Mayfield came off the bench late in the first half and led the Browns to a 21-17 comeback win. There was no turning back.

Taylor went 1-1-1 as a starter in his only season with the Browns, completing 49.4 percent of his passes for 473 yards and two touchdowns with two interceptions for a rating of 64.5. He rushed 16 times for 125 yards and a touchdown.

His career record as a starter is 23-22-1, including 0-1 in the playoffs. He has completed 61.6 percent of his passes for 9,529 yards and 53 touchdowns with 20 interceptions for a rating of 89.6.

Veteran Drew Stanton will likely serve as the Browns' No. 2 quarterback this year after filling the No. 3 role last season. The Browns will add another quarterback, too, probably a developmental player in the later rounds of the April 25-27 NFL Draft.
