ALLEN PARK -- Reggie Bush said he'd be ready for Monday Night Football. But four days away, he's not practicing.

Lions tailback Reggie Bush hasn't played since earning the Galloping Gobbler plaque for his huge day against Green Bay on Thanksgiving. He missed the first full practice of this week as well.

The Detroit Lions tailback missed practice Thursday, the team's first workout since Bush pulled his calf muscle during warmups for Sunday's game in Philadelphia. He didn't play in the game.

But Bush maintained this week that he expects to play Monday against the Baltimore Ravens.

"I look forward to getting back this week," he said.

Bush also missed the Washington game with a knee injury in Week 3, and it's not unusual for him to miss a practice or two each week to nurse bumps and bruises.

Also absent at Lions practice were DE, Ezekiel Ansah, CB Chris Houston, DE Israel Idonije, CB Darius Slay, S Louis Delmas and S John Wendling. Practice squad WR Patrick Edwards did not participate either.

Ansah injured his shoulder in the second half against Philadelphia and did not return to the game. He also battled a concussion in the preseason and missed two regular-season games with an ankle injury.

Slay had surgery six days ago to repair a reportedly torn meniscus and is expected to miss at least another game or two. Detroit hopes he returns in time for the playoffs.

Right tackle LaAdrian did practice after missing most of the Eagles game with an elbow injury.
