Browns coaches spend Tuesdays putting the game plan together.
Offensive coordinator Norv Turner will need to come up with multiple game plans, because any one of four quarterbacks could start Sunday in New England.
A team spokesman said Jason Campbell and Brandon Weeden remain in the NFL’s concussion protocol. They need to be cleared by an independent physician before returning to practice or a game.
With the uncertainty lingering, the Browns signed journeyman Caleb Hanie today. He joins Alex Tanney as the healthy quarterbacks on the roster, and one could be forced to start against the 9-3 Patriots.
A spokesman said the starter has yet to be determined. The practice week begins Wednesday.
Campbell, who started four games before suffering a concussion Nov. 24 against Pittsburgh, would be the first choice to start. He has been cleared to resume physical activity but not practice.
Weeden was diagnosed with a concussion Sunday following a 32-28 loss to Jacksonville in which he took every snap. He doesn’t know on what play he was injured.
Hanie, 28, was considered by the Browns last week when they needed a backup, but the team chose to sign Tanney off Dallas’ practice squad. Tanney has never played in an NFL game and has practiced three days with the Browns, so he isn’t an automatic choice if Campbell and Weeden can’t go.
Hanie (6-foot-2, 222 pounds) has been in the league since 2008, appearing in 10 games.
He made his only four starts for the Bears in 2011, going 0-4. He completed 50 percent of his passes for 613 yards with three touchdowns and nine interceptions for a 41.8 rating.
Hanie (6-foot-2, 222 pounds) was cut by the Ravens in the preseason and has been out of the league since. He spent last year as Denver’s third quarterback.
Hanie was undrafted out of Colorado State.
