Washington Redskins quarterback Robert Griffin III, re-injured in Sunday's wild-card loss to the Seattle Seahawks, will undergo right knee surgery this week, according to multiple media reports.
The Washington Post reported that the operation might cause Griffin to miss the start of the 2013 season, and that his rehab could drag further into next season.
The Post and ESPN cited sources saying that Griffin would have his partially torn lateral collateral ligament repaired, and that during the procedure, surgeons would determine the status of Griffin's injured anterior cruciate ligament.
Griffin traveled Monday to Gulf Breeze, Fla., to be examined by noted orthopedist James Andrews, who also is on retainer with the Redskins. Andrews was on the Washington sideline for the game against the Seattle.
Griffin initially hurt the knee Dec. 9 while playing against the Baltimore Ravens, and he later went back into the game. Andrews was present that game, and he said he and Washington coach Mike Shanahan had a miscommunication as to whether Griffin should be allowed to return to action. Griffin eventually exited the game for good after a brief return.
The following week, Griffin sat out, and backup Kirk Cousins guided the Redskins to a win over the Cleveland Browns. Griffin returned to action Dec. 23, helping Washington win a road game against the Philadelphia Eagles, and he and the Redskins captured the NFC East title with a home victory over the Dallas Cowboys in the regular-season finale.
In the playoff game against Seattle, Griffin aggravated the knee injury in the first quarter, and he was largely ineffective thereafter during the Redskins' 24-14 loss. Griffin left the game for good in the fourth quarter when the same knee was hurt again.
Griffin, the second overall pick in the 2012 draft, finished the regular season with a 65.6 completion percentage, 3,200 passing yards, 20 touchdown passes and five interceptions. He also ran for 815 yards and seven touchdowns on 120 carries.
