The Washington Redskins plan to wait until Saturday to pick their punter for Sunday’s game against the New York Giants at MetLife Stadium.

With their punter, Sav Rocca, plagued by a knee injury suffered while jogging after a practice this week, the Redskins had a workout Friday at Redskins Park for three punters. The group included former Pittsburgh Steelers punter Daniel Sepulveda and former Philadelphia Eagles punter Chas Henry.

Coach Mike Shanahan said Friday that the Redskins planned to have Rocca test his knee Saturday to see if he can punt. If he can’t, the team would have to make a roster move Saturday for Sunday’s game.

Another complication is that Rocca serves as the Redskins’ holder on field goals and extra points. That duty could fall to the new punter, if the Redskins make a change, or to backup quarterback Kirk Cousins. The team already has had to switch kickers and long snappers this season.

The Redskins also worked out two free agent cornerbacks Friday, Devin Holland and D.J. Johnson.

Three Redskins cornerbacks — starter DeAngelo Hall and reserves David Jones and Cedric Griffin — were on the team’s injury report Friday. Jones was listed as questionable for Sunday’s game because of an Achilles’ tendon injury. Griffin was listed as questionable because of a hamstring injury. Hall was listed as probable with a knee injury.
