RB Zac Stacy probable for Sunday

EARTH CITY, Mo. -- It had been trending this direction all week but barring a setback, the St. Louis Rams will have their trio of concussed players, including running back Zac Stacy, available Sunday against the San Francisco 49ers.

Stacy, cornerback Trumaine Johnson and left guard Chris Williams practiced fully on Friday and are officially listed as probable on the team's Friday injury report. That group has gone through the necessary steps to be cleared by doctors to return and appears on course to play in San Francisco.

Clearly, having all three key starters available is a positive thing for the Rams, particularly in a game where all hands on deck will be required against the Niners.

While Stacy has been having much success running the ball of late, it's Johnson's likely return that might be the most imperative. That's because the Rams lost Cortland Finnegan to injured reserve because of an eye injury last week and cornerback Brandon McGee suffered a foot injury in Thursday's practice that kept him out Friday and has him designated as questionable for Sunday.

With Johnson's return on track, the Rams would have Johnson, Janoris Jenkins and Quinton Pointer as the only healthy available cornerbacks. Safety Rodney McLeod can also play in the slot and has in sub-packages a number of times this season.

Here's how the rest of the Rams' Friday injury report shapes up:

Questionable: McGee, S T.J. McDonald (shin), G Harvey Dahl (knee)

Probable: Stacy, Johnson, Williams, LB Will Witherspoon (not injury related), DE Eugene Sims (foot)
