Shaw will undergo surgery on his thumb this week. According to Northeast Ohio Media Group, Shaw will likely be placed on injured reserve for the season.
“I feel for Connor because he has worked extremely hard,” said Browns head coach Mike Pettine. “He's a competitor and has had a great offseason and a good camp so far. He is good for the quarterback room and it's unfortunate that this injury won't allow him to compete.”
The 23-year-old Shaw was expected to be the Browns third-string quarterback behind Josh McCown and Manziel. Pettine has not yet declared a starter for the regular-season opener, however McCown entered training camp as the first-string quarterback.
