Falcons LB Pat Angerer out with concussion

Falcons linebacker Pat Angerer has yet to be cleared through the league’s concussion protocol after suffering a head injury during practice on Tuesday, coach Mike Smith said.

Angerer was able to walk off the field with team trainer Marty Lauzon after suffering the injury. He’s been practicing at inside linebacker with the second-team defense.

According to the concussion protocol, doctors and trainers are monitoring Angerer to determine when he returns to his baseline functioning. Once Angerer’s symptoms have subsided he will undergo more tests and, if he makes progress, he will be allowed to increase his physical activity as long as no symptoms occur.

Angerer, 27, is trying to make a comeback after undergoing microfracture knee surgery in December. The Colts selected Angerer in the second round of the 2010 draft out of Iowa and he started 39 of 53 games for them before ending last season on injured reserve.
