SAN DIEGO (AP) -Shawne Merriman was fine Friday, even if his right foot wasn't.

``I still got two more days to get it right,'' the Chargers' star outside linebacker said.

Merriman, tied for the NFL lead with 12 1/2 sacks, didn't practice Friday, but left no doubt he will play when the Chargers try to extend their winning streak to eight Sunday night against the visiting Kansas City Chiefs.

Merriman said his foot is sore from wearing different cleats.

``I wear linebacker cleats during the week, then the lighter ones - like the defensive backs wear - during the games,'' Merriman said.

Like a baseball player swinging a weighted bat while on-deck, Merriman said practicing in the heavier cleats makes him lighter on his feet on game day.

While the transition from one cleat to another can play havoc with his foot, Merriman speculates he'll be more than ready Sunday to play havoc with the Chiefs.

In the two games since his return from a four-game NFL suspension for flunking a steroid test, Merriman has four sacks and four forced fumbles.

``I sat out for four weeks, so now sitting out a full practice or two is not as bad,'' said Merriman, the 2005 Defensive Rookie of the Year and a Pro Bowl starter. ``You learn how to deal with it, but I don't like missing any kind of football.''

Also sitting out Friday were linebacker Marques Harris, who hasn't practiced all week due to a strained hamstring, and offensive linemen Scott Mruczkowski, who has a knee injury and will miss Sunday's game.
