The Ravens lost centers Jovaughn Gwyn and Ethan Pocic to long-term injuries in last Sunday’s win over the Ravens and both players were moved to the injured reserve list on Saturday.

Gwyn fractured his fibula and Pocic hurt his knee after replacing him. Danny Pinter is also on injured reserve, so the team turned to first-round pick Vega Ioane last Sunday and he’s expected to remain at the position for this Sunday’s game against the Titans. Andrew Vorhees replaced Ioane at right guard against Dallas.

The Ravens did not fill either roster spot, but they have elevated guard Kyle Hergel from the practice squad.

Hergel signed with the Ravens this week and he played for offensive coordinator Declan Doyle in Chicago last season.
