The Falcons have lost a second center for the season, announcing today (Twitter link) that Peter Konz has been placed on injured reserve after suffering a knee injury this weekend. The team signed offensive lineman Jonathan Scott to fill the newly-opened roster spot.

Konz, 25, started 25 contests during his first two seasons with the Falcons after being drafted in the second round in 2012, but was relegated to a backup role to open the 2014 season. When center Joe Hawley was placed on injured reserve, Konz slid back into the starting lineup, but will now see his campaign end after just seven games.

Earlier today, ESPN’s Adam Caplan had reported (via Twitter) that while the results of Konz’ MRI weren’t in yet, the feeling was that he had at least suffered a significant sprain. It appears the MRI confirmed the injury is a serious one, and the designation to return wasn’t an option for the Falcons, who already used that spot on safety William Moore earlier in the year.

As for the Falcons’ newest lineman, Scott hasn’t played in a regular season NFL game since 2012, but has plenty of experience, having logged 35 total starts for the Lions, Bills, Steelers, and Bears.
