Early indications suggest his latest ankle injury is similar.
"It's in that area," coach Pete Carroll told reporters after the game, according to Danny O'Neil.
Last season, Okung suffered a high ankle sprain Aug. 21 against Green Bay. He did not play in a game until Oct. 3, a span of 43 days. Okung suffered a high sprain on his other ankle Oct. 24 against Arizona. He did not play in another game until Nov. 21, a span of 28 days.
Seattle opens its regular season Sept. 11, 31 days from the injury suffered Thursday night.
We do not know for certain the extent of the damage or how long Okung might need to recover. But if the timetable is similar to the ones Okung followed previously, he would be returning sometime during the first three weeks of the regular season.
