Falcons Irons, Robinson out for season

The Falcons put cornerback David Irons and wide receiver Laurent Robinson on injured reserve Tuesday, ending their seasons.

Irons, a key player on special teams, suffered a torn anterior cruciate ligament Sunday against Tampa Bay. Robinson has been battling a hamstring injury.

The Falcons elevated safety Eric Brock from the practice squad and signed free-agent tight end Marcus Pollard to the 53-man roster. The Falcons also signed cornerback Darius Vinnett and offensive lineman Michael Butterworth to the practice squad.

Irons, a former Dacula High standout who played at Auburn, made the team last season after being drafted in the sixth round (194th overall). Last season, he lead the team with 13 tackles on special teams and had one fumble recovery. He played in five games this season and was inactive for nine games.

Robinson, a third-round pick in 2007, sprained his knee against Kansas City early this season and missed four games. He was active for the next three games before missing the past four games with the hamstring injury.

“His hamstring has not been getting a whole lot better,” Falcons coach Mike Smith said Monday. “He had a setback in practice last week.”

Robinson has five catches for 52 yards this season.

Brock (6-0, 202 pounds), was signed by the Falcons as a free agent in May and waived on August.

Pollard (6-3, 255), is in 14th NFL season. He signed with the Falcons August, but was released following training camp.

Butterworth (6-7, 298) re-joins the Falcons after being waived by the team following training camp.

Darius Vinnett (5-8, 170) played with St. Louis last season.
