But he wasn't the only notable casualty of NFL roster cuts, which mandated that teams trim rosters to 53 players by 4 p.m. Saturday.
Daniel was competing with former Hawaii quarterback—and fellow Heisman Trophy candidate—Colt Brennan for the right to play behind starter Jason Campbell and backup Todd Collins, but Brennan was put on injured reserve with a torn hamstring and hip injury.
An undrafted free-agent, Daniel agreed to a deal with the Redskins after a record-breaking career with the Tigers from 2005-08. Though he was not expected to beat out Brennan, a sixth-round pick of Washington in 2008, Daniel put up far better numbers in the preseason—albeit in two fewer games.
In two preseason appearances, Daniel threw three touchdown passes and no interceptions while completing 14 of 24 passes for 143 yards and a rating of 115.1.
Conversely, Brennan, who earned the No. 3 quarterback role last season with a string of strong exhibition performances, compiled a 49.5 rating while completing 10 of 14 passes for 249 yards, one touchdown, and three interceptions in four games.
Brennan started to make late push to retain his title with a strong performance against Jacksonville in Washington's final preseason game, but a re-aggravation of the hamstring injury led to the move to the injured reserve list.
According to Washington's official website, Daniel may still find a spot on the practice squad if he's able to clear waivers.
NFL teams can assemble eight-man practice squads Sunday.
