The MRI exam conducted Monday morning on the right knee of Redskins safety DeAngelo Hall confirmed the fears team doctors had on Sunday. Hall tore the anterior cruciate ligament and must have surgery, a person with knowledge of the situation confirmed.

Hall suffered his injury late in the third quarter of Sunday’s win over the New York Giants. Originally, the team announced that he had suffered a right knee sprain. But Hall said after the game that doctors told him they believed the ACL was torn. The MRI exam confirmed those suspicions.

ABC-7 first reported news of the findings.

It’s the second straight week that the Redskins have lost one of their locker-room leaders to season-ending injury. Last week, nose tackle Kedric Golston went on injured reserve with a hamstring tear that required surgery to repair.

This marks the second time in the past three seasons that Hall has had his season ended prematurely because of injury. In 2014, he tore his right Achilles’ tendon three games into the season. Hall returned last year and made the transition from cornerback to safety midway through the season. The 13th-year veteran, who turns 33 in November, now faces another long road back, and it remains to be seen if Hall will play another season. Hall has one more year left on his contract. However, the $4.25 million salary for 2017 isn’t guaranteed.

Now in his ninth season with the Redskins, Hall is among the longest-tenured members of the team, second to Golston, who was in his 11th season. Hall has made the Pro Bowl three times — once as a member of the Redskins in 2010 — and he shares the NFL record for four interceptions in one game.
