The Patriots showed no patience with the last returner to make a mistake, so the new guy better know where the bar is set.

According to Mike Reiss of ESPN.com, the Patriots are signing receiver/return man Damaris Johnson.

He’ll replace Chris Harper, whose muffed punt Sunday night turned the tide against the Broncos and cost him his job Monday.

Johnson, who entered the league as an undrafted rookie from Tulsa, spent two seasons with the Eagles and last year with the Texans. He hasn’t been able to find work this year, but has averaged 25.1 yards per kickoff return and 9.5 yards per punt return.
