Redskins defensive end Jason Hatcher will have arthroscopic surgery on Thursday on his sore left knee.
Hatcher missed this week's minicamp at Redskins Park. Hatcher, 31, will miss four-to-six weeks, putting his status for the start of training camp in doubt.
Signed to a four-year, $10.5 million deal this offseason after spending his entire career with the Dallas Cowboys, Hatcher is expected to bolster Washington's defensive front. He finished with 11 sacks last season.
"It's old stuff, man. I don't know a particular play, but I don't want to go into the season 80 percent," Hatcher said. "I want to be 100, so I can be the best Hatch for this football team, for this defense, so I can help our team get better."
Hatcher's surgery will be performed by renowned surgeon Dr. James Andrews.
"We don't feel like it's a long-term thing," Redskins coach Jay Gruden said. "Any time you have a surgery there's a little bit of a concern. But I think from what I'm told, the severity of it is not that great...There was no major damage in there whatsoever."
