Galaxy-Seattle: Medical report

Todd Dunivant is ready to go for the Galaxy and Jeff Parke is unlikely to suit up for the Sounders in Sunday's clash at Home Depot Center (ESPN and ESPN Deportes, 6 p.m.)

More important: David Beckham should be at full strength after testing his Achilles' tendon in last week's first leg on Qwest Field's artificial surface. The English midfielder, who missed six months after rupturing the left Achilles' last March while playing for AC Milan, said after the Galaxy's 1-0 victory in Seattle that it was sore throughout the match.

“It's taken me a few days to get over it, I must admit,” Beckham said Friday. “It was the first time I played on [artificial] turf since the Achilles'; I'm almost recovered from it. … It's an aching kind of thing for a good few days. After each game, there's an aching effect, but after the game the other day there was more so.”

It seems everyone was affected by the Qwest turf in some manner.

“When you play on turf, everyone comes off the field sore,” Galaxy coach Bruce Arena said. “A bunch of guys were hurting on Tuesday. The surface is tough. I think the soreness is kind of natural.”

IN THE BACK: Dunivant, who missed the first leg with a hamstring strain, practiced fully all week and likely will return at left back. Eddie Lewis was exceptional in his place in the first leg.

Parke, who sprained an ankle in the game, didn't practice this week, so Tyrone Marshall, who was part of the Galaxy's 2002 and 2005 MLS Cup title-winning teams, likely will team with former UCLA star Patrick Ianni in the middle of the Sounders' defense.

Marshall, who spent 5½ seasons with the Galaxy and was traded to Toronto FC in June 2007 for Edson Buddle, started 14 of Seattle's first 15 league games but was supplanted in the lineup as the Sounders took off in the second half of the season with a Parke-Ianni partnership in the back.

“Tyrone is fine. He is an experienced player. He is a player who has been in a lot of big games,” Sounders coach Sigi Schmid said Saturday. “It’s a situation where we went on a very good run with Parke and Ianni at center backs, and they continued to play well. Tyrone was knocking on door, but because of the success we were having, there was no need to change. … I feel pretty confident in his abilities, and I know he feels very confident in his abilities. He’s ready to play.”
