Flowery Branch – Falcons running back Michael Turner (groin) and wide receiver Julio Jones (hamstring) returned to practice and were limited participants Friday.

Both players, who had not practiced this week, were listed as questionable on the team’s official injury report for Sunday’s 1 p.m. game against the Houston Texans.

Also, starting strongside linebacker Stephen Nicholas (thigh) did not practice and was listed as doubtful along with cornerback Kelvin Hayden.  Mike Peterson will take his spot in the lineup if he can’t play.

Cornerback Brent Grimes (knee surgery) was officially declared out of the game.

ROSTER MOVE: The Falcons released defensive tackle Carlton Powell and added quarterback John Parker Wilson to the active roster on Friday.

The Minnesota Vikings, who released Donovan McNabb on Thursday, tried to sign Wilson off the Falcons’ practice squad.
