He quickly said a prayer.

Shortly after the first quarter play on which Davis was injured, the Redskins announced that the fifth-year pro had an Achilles’ tendon injury and would not return.

 Davis, who had recorded 23 catches for 312 yards, faces a lengthy recovery process, but Williams expects him to make a strong comeback.

 “It’s heartbreaking. That’s one of my best friends on the team, and he’s such a tough guy. To see him limping, I knew it was something serious. I said a prayer for him. But I know he’ll be good. He works hard, he’s very diligent.”

 Suspended for the final four games of the 2011 season for failing multiple drug tests, Davis and Williams leaned on each other as they worked their way back to redemption. Both stepped up as leaders this season and had aspirations of producing Pro Bowl seasons and helping to turn around the team’s fortunes this year.

Now Davis willl have to watch from the sidelines. But Williams said that he will make sure that Davis remains focused.

 “We’re real close, so I’m going to talk to Fred,” Williams said.
