Browns quarterback Connor Shaw will undergo surgery on his right thumb.
Shaw got hurt during Thursday's exhibition opener against Washington. The second-year QB completed 5 of 10 passes for 64 yards in the 20-17 loss.
The Browns said Shaw, who started Cleveland's season finale last season, will miss "an extended period of time." Shaw was listed behind Josh McCown and Johnny Manziel on the team's depth chart, but the Browns are high on the former South Carolina star, who showed toughness and potential in the final game last season against Baltimore.
Filling in for an injured Manziel, Shaw completed 14 of 28 passes for 177 yards against the playoff-bound Ravens. He finished the game despite a dislocated finger and bruised kidney.
