Browns quarterback McCoy out with concussion

Browns quarterback Colt McCoy has been ruled out for Sunday and tight end Benjamin Watson is done for the season, both victims of concussions.

McCoy is still experiencing headaches and having other symptoms from his concussion, sustained last week on an illegal helmet-to-helmet hit by Pittsburgh linebacker James Harrison.

The second-year QB was sent home for the fourth time this week before Friday's practice. Afterward, coach Pat Shurmur announced that backup Seneca Wallace will start in McCoy's place on Sunday at Arizona.

McCoy, who had his head snapped back by Harrison's shot to his face mask, is not travelling with the team. Shurmur said there has been no discussion about putting the second-year QB on IR.

The Browns also placed Watson on injured reserve, ending his season with three games left. Watson suffered his third concussion since July last week against the Steelers. Watson, who was Cleveland's leading receiver last season and had 37 catches this year, visited a specialist on head injuries earlier this week.

"He's disappointed," said Shurmur, who has spoken with Watson. "But it's the right course of action right now. He wishes he could still be with us but we'll make this move now and hopefully get him back next year."

Shurmur said Watson did not discuss the possibility of retiring with him.

Shurmur added that fullback Owen Marecic is also out this week. He also sustained a concussion —- his second in a month —against the Steelers.

To replace Marecic, the Browns have activated fullback Eddie Williams.
